.NET Core 1.0 - How ready for use?

courtlanda last edited by

On 27 June, the version of NET Core 1.0 and a number of associated libraries were released.
Issues:
How is NET Core in the current state available for use as a basis for web applications? Does it make sense to move on to him now or just study it?
How stable is NET Core? Isn't he too much of a moustache for industrial applications?
What's the problem / underwater stones are in it now, which is the most disturbing thing?
What parts API.NET Framework have not been implemented in NET Core? What are the new API missing in the NET Framework?
P.S. So far, only this (partial) response, as of April: https://stackoverflow.com/questions/36422152/is-net-core-1-0-ready-to-be-used-on-a-full-scale-production-site-yet

I'm not ready because it's not even about MS. And if this platform is supported by other clouds other than Azure.

There are three platforms for the moment, if you can say so. .Net: собственно .Net Framework♪ .Net Core and Xamarin♪ Each platform runs an API set.If you have the task of writing a library that would allow you to use it for different platforms, then you'll be assisted. .Net Standard♪.Net Standard ♪ It's not another platform..Net♪ You can't create a complete file like a console type. .Net Standard♪ You can only write a library. dll♪.Net Standard ♪ this specification. Determining the API set, which each platform should implement. It's like a contract between the three parties.by signing them to respect. This specification allows you as a developer to create a library that can be used for all three platforms.

Apparently you need to define the virtual public property modelo of Paises relatedExample:public int PaisOrigenID { get; set; } public int PaisProcedenciaID { get; set; } [ForeignKey("PaisOrigenID,PaisProcedenciaID")] public virtual Paises Paises { get; set; } other way[ForeignKey("Paises")] public int PaisOrigenID { get; set; } public virtual Paises Paises { get; set; }

First of all, I recommend that we look at the references that I've mentioned quite often ( https://ru.stackoverflow.com/a/916772/213987 (e.g.) asp.net - CQRS + Mediatr Annex. Here. https://github.com/JasonGT/NorthwindTraders Here. https://www.youtube.com/watch?v=_lwCVE_XgqI&index=7&list=LLFAXGDZ1WrEdqvPUmNRPQcA&t=0s I don't know if you'll use Mediatr, but in any case, we'll talk about two classes:Query is the class for input requirementsResult is the response classIn the Terms of MediatR, I would write that:public class Query : IRequest<Result> { } Accordingly, the controller would look like:public class PlaceController : BaseController { public PlaceController(IMediator mediator) : base(mediator) { } public async Task<IActionResult> List(Places.List.Query query, CancellationToken cancellationToken) { if (!this.ModelState.IsValid) // какая-то обработка ошибок var result = await this.Mediator.Send(query, cancellationToken); return this.View((query, result)); } (You may not use c# boxes, but let's say you're gonna have your class coat, you can be generic."If you want to go to the SPA application to react/vue/angular, your api counteroler will make it even easier to go to Query's entrance, you'll give Result the exit:public class CategoryController : BaseApiController { public CategoryController(IMediator mediator) : base(mediator) { } [HttpPost] public async Task<object> List(Categories.List.Query query, CancellationToken cancellationToken) { var result = await this.Mediator.Send(query, cancellationToken); return result; } } It's easier if you want to go to Razor Pages:public class ListModel : PageBaseModel { public ListModel(IMediator mediator) : base(mediator) { } [BindProperty(SupportsGet = true)] public Accounts.List.Query Query { get; set; } public Accounts.List.Result Result { get; private set; } public async Task<IActionResult> OnGetAsync(CancellationToken cancellationToken) { this.Result = await this.Mediator.Send(query, cancellationToken); return this.Page(); } } In the case of asp.net, you need an annex to the exit and Result and Query - that, according to Query, your View will paint on the page the parameters of the request, namely:filterssortingadvocacyIt is the contents of your Query, in private cases, there may be no parts, such as the table does not provide for sorting.You can directly break your Query class into three parts by grouping the fields with the help of the region or making further deviations between the fields. Let's say:public class Query { // Filters public bool HideArchieved { get; set; } public DateTime? FromDate { get; set; } public DateTime? ToDate { get; set; } // Pagination public int PageSize { get; set; } public int PageNumber { get; set; } } I'd prefer to make a panic in a separate class:public class PagedQuery { public int PageSize { get; set; } public int PageNumber { get; set; } public int ToSkip => (this.PageNumber - 1) * this.PageSize; public Paging GetPaging(int total, string url) { return new Paging(this.PageSize, this.PageNumber, total, url); } } And I do, like,public class Query : PagedQuery, IRequest<Result> { public bool HideArchieved { get; set; } public DateTime? FromDate { get; set; } public DateTime? ToDate { get; set; } } A little resignation, a few words about how the request looks. For MediatR, you'll be writing like this:[UsedImplicitly] public class Handler : BaseHandler, IRequestHandler<Query, Result> { public Handler(ApplicationDbContext applicationDbContext) : base(applicationDbContext) { } public async Task<Result> Handle(Query request, CancellationToken cancellationToken) { IQueryable<Place> query = this.ApplicationDbContext.Places; if (request.HideArchieved) { query = query.Where(x => x.Archieved == false); } var places = await query.OrderByDescending(x => x.Id) .Skip(request.ToSkip) .Take(request.PageSize) .AsNoTracking() .ToArrayAsync(cancellationToken); return new Result { Places = places, PlacesCount = query.Count(), }; } } You can turn in the repository, you know that you have three distinct phases within the processor: the final query is collected from filters, pole sorting, and pagination parameters.And now it's time to talk about what your performance looks like.@using Microsoft.AspNetCore.Http.Extensions @model (Places.List.Query Query, Places.List.Result Result) @{ ViewBag.Title = "Места игр"; } <h2>@ViewBag.Title</h2> <p><a asp-action="Create" class="btn btn-outline-secondary">Создать новое место игр</a></p> It will also consist of several parts: first, a set of filters will be shown, we will pass the Query parameters there:<partial name="ListFilter" model="Model.Query" /> After that, we will draw our own table with poles and sorting:<partial name="ListResult" model="Model.Result.Places" /> And after that, we'll depict the pagination, the template can be put peacefully in a shared view, it's the same for everyone:<partial name="Pagination" model="Model.Query.GetPaging(Model.Result.PlacesCount, Context.Request.GetDisplayUrl())" /> Let's see the first part - filters:@model Places.List.Query <div class="row"> <div class="col-sm-12 col-md-12"> <div class="alert alert-info"> <form method="get" class="form-inline"> <div class="form-group"> <label asp-for="HideArchieved"></label> <input asp-for="HideArchieved" class="form-control" /> </div> <input type="hidden" asp-for="PageSize" /> <input type="hidden" asp-for="PageNumber" /> <button type="submit" class="btn btn-secondary">filter</button> </form> </div> </div> </div> We carefully painted the filters and put it in the hidden grading parameters. If someone burns the filter button, we've got all the data in the GET parameter stored.I'll drop the table.It's simple at first sight:@model Paging <div class="row"> <div class="col-sm-12 col-md-12"> <nav aria-label="Page navigation example"> <ul class="pagination"> @if (Model.IsFirst()) { <li class="page-item disabled"><a class="page-link" href="@Model.FirstUrl"><<</a></li> <li class="page-item disabled"><a class="page-link" href="@Model.PrevUrl"><</a></li> } else { <li class="page-item"><a class="page-link" href="@Model.FirstUrl"><<</a></li> <li class="page-item"><a class="page-link" href="@Model.PrevUrl"><</a></li> } @foreach (var i in Model.GetPaging()) { if (Model.IsCurrent(i)) { <li class="page-item active"> <a class="page-link disabled" href="@Model.GetUrl(i)">@i</a> </li> } else { <li class="page-item"> <a class="page-link" href="@Model.GetUrl(i)">@i</a> </li> } } @if (Model.IsLast()) { <li class="page-item disabled"><a class="page-link" href="@Model.NextUrl">></a></li> <li class="page-item disabled"><a class="page-link" href="@Model.LastUrl">>></a></li> } else { <li class="page-item"><a class="page-link" href="@Model.NextUrl">></a></li> <li class="page-item"><a class="page-link" href="@Model.LastUrl">>></a></li> } </ul> </nav> </div> </div> Everything interesting is carried out in Paging class:public class Paging { public Paging(int pageSize, int pageNumber, int total, string url) { this.PageSize = pageSize; this.PageNumber = pageNumber; this.Total = total; this.Url = url; } private int PageSize { get; set; } private int PageNumber { get; set; } private int Total { get; set; } private string Url { get; set; } public int[] GetPaging() { const int maxBefore = 5; const int maxAfter = 5; var first = this.PageNumber - maxBefore; if (first < 1) first = 1; var last = this.PageNumber + maxAfter; if (last > this.MaxPageCount) last = this.MaxPageCount; return Enumerable.Range(first, last - first).ToArray(); } private int MaxPageCount => (int)Math.Ceiling((double)this.Total / this.PageSize); public bool IsCurrent(int i) => this.PageNumber == i; public bool IsFirst() => this.IsCurrent(1); public bool IsLast() => this.IsCurrent(this.MaxPageCount); public string GetUrl(int i) { var uri = new Uri(this.Url); var baseUri = uri.GetComponents(UriComponents.Scheme | UriComponents.Host | UriComponents.Port | UriComponents.Path, UriFormat.UriEscaped); var query = QueryHelpers.ParseQuery(uri.Query); var items = query.SelectMany(x => x.Value, (col, value) => new KeyValuePair<string, string>(col.Key, value)).ToList(); items.RemoveAll(x => x.Key == "PageNumber"); var qb = new QueryBuilder(items); qb.Add("PageNumber", i.ToString()); var fullUri = baseUri + qb.ToQueryString(); return fullUri; } public string FirstUrl => this.GetUrl(1); public string LastUrl => this.GetUrl(this.MaxPageCount); public string PrevUrl => this.GetUrl(this.PageNumber - 1); public string NextUrl => this.GetUrl(this.PageNumber + 1); } How is that done? The principle is simple: it takes the current url page, it removes the radium and adds again, but already with the meaning we need. (Done by two remarkable nuget-packets - Microsoft.AspNetCore.WebUtilities and Microsoft.AspNetCore.Http. Extensions, I'm sending the details here.

Looks like you shot and misconfigured class relationships... usually this kind of mistake is for that reason.You can arm the class hierarchy the following waypublic class ClassA { public int Id { get; set; } public List<ClassB> B{ get; set; } } public class ClassB { public int Id { get; set; } public ClassA A { get; set; } public List<ClassC> C{ get; set; } } public class ClassC { public int { get; set; } public ClassB B { get; set; } } Each is a relationship from one to many and see that at each lower level there is a reference to the higher.Then in the context you indicate the relationships:modelBuilder.Entity<ClassA>().HasMany(s => s.B).WithOne(s => s.A); modelBuilder.Entity<ClassB>().HasMany(s => s.C).WithOne(s => s.B); And finally you do the consultation:List<ClassA> as = context.ClassesA .Include(x => x.B) .ThenInclude(x => x.C) .ToList(); On the other hand, what is your need to have entity classes that are parcial, primary key string type and ICollection Like virtual?EntityFramework Core takes properties Id as PK by generating the table in the Migration by default. It is only necessary to use [key] when not following the standard, but I recommend using it to facilitate future maintenance (possibly by other equipment).

On the question of complexity, the listed should not be compared with one parameter.You know, you know, it's a thing that treats one class of technology and that makes it easy to compare.To figure this out, we have to go back to the past.ASP was first. It was a "slightly subdirected php-cheek from Microsoft," where the html and code were blended, but there was already a strict typology and the possibility of connecting COM-components.This has opened up a great deal of opportunities to post the websites with active content of technology server-side, because the JS was at this point very well conceived only to draw snowflies on the front page between December and March.Then, as the ASP abrreviat has already been known to the audience (and Microsoft is very fond of the three-block abreviations) ASP appeared. NETThis was a huge step forward that allowed NET Framework to be applied on the Web server. The "possibility" here means the possibilities of languages (C#, VB.NET, and it seems F# - and they're all in an intermediate byte-code, which was done with NET runtime. But since the NET Framework (versions 1, 2, 3, 3.5, 4, 4.5, 4.51, 4.52, 4.6, 4.7 and 4.8) was only under the vindu, it was nailed to IIS and Microsoft Server, which, of course, caused ironic laughter in all bearded linux-admins.At the same time, ASP.NET MVC emerged, which identified the application of the Model-View-Sontroller template in ASP.NET. In fact, instead of a randomly grouped code, it was suggested that the code should be divided into essentially Model, View or Controller.NET Core was born in order to become a paid-up. Who works the same way on both vinda and the linux. It's a huge freymvork, of scale comparable to Spring' from the Java world. Its part relevant to WEB is named ASP.NET Core. It had the possibility of using the MVC template, which was likely to imply ASP.NET Core MVC.Because it's boring to write a lot of abstracts, names have narrowed down, for example, from ASP.NET Core MVC to NET Core MVC and, in fact, who's in the middle.In fact, there are:♪ NET Core is the whole frimevork.ASP. NET Core is part of the fraimvor buried under WEB.ASP. NET Core MVC is part of the foam box stored under WEB, using the MVC templateTherefore, in returning to the question, the comparison should be based on such a scheme:There is ASP or ASP in the name of technology. NET? If so, then this technology has something to do with WEB. If it's just "ASP" - it's likely NET's just forgotten to sign 'cause ASP technology is very old and it's no longer in use.Is there a Core in the name of technology? If so, the technology is cross-splatform and is based on the foil of NET Core. If there is a Framework in the name of technology or simply no Core word - it is likely that there is a NET Framefork that only operates WindowsIs there a MVC in the name of technology? If yes, the model-View-Controller division template is applied, if not, to the extent that it is not. Or cut down some of the abbreviations, considering everyone's gonna figure it out.So the answer to you. current The question (and prior to the questioning, you mentioned the use of the MVC template) as follows:| Название технологии | WEB или общего назначения? | Кроссплатформенная? | | | | | | ASP.NET Core | WEB | да | | | | | | .NET Core | общего назначения | да | | | | | | ASP.NET? | WEB | нет, только Windows | Is that clearer?

You saw this in code, it can be called code tags.Strictly it is a comment like any other. It can have a specific meaning for some tool. It is common IDEs or at least extensions of them have something they search the code looking for comments starting with:TODO: ("to do") Someone [I] needs to get this urgentFIXME: ("me fix") It has a mistake that needs to be fixed here, but it works (TOFIX:)HACK: ("gambi") There was no other way to resolve the deadline, then betterXXX: ("attention") Some editors highlight comments with this as something important without giving specific semanticsDONE: ("made") To warn you TODO It's settled. When to remove this?UNDONE: ("defect") I needed to get back to the original for some reasonASAP: ("as fast as possible") You need to get this urgentREMOVE: ("remove") This code has been placed only to test something and must disappearNOTE: ("annotation") Just to let you know you have something important nowBUG: ("failure") Has a bug known here that needs to be tidy - specialization of FIXME - usually have an associated ticket numberISSUE: ("question") There is a doubt here whether it should be soERROR: ("error") Has a reproducible error here - FIXME specializationBROKEN: ("breaking") does not go ahead even, no use insist - specialization of FIXMEGLITCH ("failure") Something strange occurs here in a very specific situationREVIEW: ("revise") Review that for me, used where you usually do peer reviewWTF: ("that p0rr@ is that?") They've done a really big shit here.And similar. .The tools catalogue these comments somewhere specific, not just in the code to highlight that the code is not complete or at least needs special attention for programmers not to ignore by accident.Many allow you to set up whatever you want, but exaggerate can start making it difficult to use, in general the first 3 are very useful (for the VIM only the room is considered), the others are variations, specializations, exaggerations or require better tools.In general there is a more detailed description after the two points. This Tag specific serves to help the tool identify the semantics of this comment.This is a practice of organized programmers. Of course, if you stick a lot of them and drop it gives you the same as not to use. In general they must be transitory.Some teams even forbid code with that to be committed, except in cases that are for communication with other team members. The argument is that if it is a planned and not implemented thing should stay in the documentation, if it is something that is missing to fulfill the planned implementation then the commit cannot be done until complete. The reality prevents the flow from being in fact like this, the most that happens is people take it out of the code and mark it elsewhere easier to forget, just to break the silly rule.Does anyone remember others?

To run net core there is a specific framework that you have to install on the computer where you run either windows or linux, also to run framework 4.7 or any of its previous versions, implies installing on the windows computer, the libraries that support it.Link of .net core https://www.microsoft.com/net/download/core Link of framework 4.7 https://www.microsoft.com/en-us/download/details.aspx?id=55170 The only advantage there really is that it is possible to reuse some code, but even if they become portable libraries.

For Excel, for example, this code works:Application app = new Application(); app.Visible = true; var books = app.Workbooks; var book = books.Add(); Worksheet sheet = book.ActiveSheet; Console.WriteLine(sheet.Name); sheet.Name = "Hello from .NET Core"; There's no such thing.sheet.Cells[1,1] = "Hello from .NET Core"; //ноль эффекта In order to use the Range interface, which later uses the connection, it will require a more complex code:using System; using System.Runtime.InteropServices; using ComTypes = System.Runtime.InteropServices.ComTypes; using Microsoft.Office.Interop.Excel; namespace NetCoreTest { class Program { static void Main(string[] args) { Application app = new Application(); app.Visible = true; var books = app.Workbooks; var book = books.Add(); _Worksheet sheet = book.ActiveSheet; Range r = sheet.get_Range("A1"); SetProperty(r, "Value", "Hello from .NET Core"); Console.ReadKey(); } //Устанавливает свойство COM-объекта с использованием позднего связывания public static void SetProperty(object obj, string property, string value) { int dispId = GetDispId(obj, property); InvokePropertySetter(obj as IDispatch, dispId, value); } const uint DISPATCH_METHOD = 0x1; const uint DISPATCH_PROPERTYGET = 0x2; const uint DISPATCH_PROPERTYPUT = 0x4; // Получение DispId для указанного метода (свойства) COM-объекта с использованием позднего связывания // Источник: https://github.com/dotnet/corefx/issues/19731 public static int GetDispId(object rcw, string methodName) { IDispatch dispatchObject = rcw as IDispatch; if (dispatchObject == null) { Console.WriteLine("Passed-in argument is not a IDispatch object"); return -1; } int[] dispIds = new int[1]; Guid emtpyRiid = Guid.Empty; dispatchObject.GetIDsOfNames( emtpyRiid, new string[] { methodName }, 1, 0, dispIds); if (dispIds[0] == -1) { Console.WriteLine("Method name {0} cannot be recognized.", methodName); } return dispIds[0]; } public static object InvokePropertySetter(IDispatch target, int dispId, string val) { const int DISPID_PROPERTYPUT = -3; IntPtr pArg = IntPtr.Zero; IntPtr pNamedArgs = IntPtr.Zero; IntPtr pStr = IntPtr.Zero; IntPtr dispIdArray = IntPtr.Zero, tmpVariants = IntPtr.Zero; if (target == null) { Console.WriteLine("Cannot cast target to IDispatch."); return null; } try { pStr = Marshal.StringToBSTR(val); Variant variant = new Variant(); variant.vt = 8; //VT_BSTR variant.p = pStr; pArg = Marshal.AllocHGlobal(Marshal.SizeOf(variant)); Marshal.StructureToPtr(variant, pArg, false); pNamedArgs = Marshal.AllocHGlobal(4); Marshal.WriteInt32(pNamedArgs, DISPID_PROPERTYPUT); var paramArray = new ComTypes.DISPPARAMS[1]; paramArray[0].rgvarg = pArg; paramArray[0].cArgs = 1; paramArray[0].cNamedArgs = 1; paramArray[0].rgdispidNamedArgs = pNamedArgs; ComTypes.EXCEPINFO info = default(ComTypes.EXCEPINFO); object result = null; uint puArgErrNotUsed = 0; target.Invoke(dispId, new Guid(), 0x0409, ComTypes.INVOKEKIND.INVOKE_PROPERTYPUT, paramArray, out result, out info, out puArgErrNotUsed); return result; } finally { if (pStr != IntPtr.Zero) Marshal.FreeBSTR(pStr); if (pArg != IntPtr.Zero) Marshal.FreeHGlobal(pArg); if (pNamedArgs != IntPtr.Zero) Marshal.FreeHGlobal(pNamedArgs); } } [DllImport("ole32.dll")] public static extern int CLSIDFromProgID([MarshalAs(UnmanagedType.LPWStr)] string lpszProgID, out Guid pclsid); [Guid("00020400-0000-0000-c000-000000000046")] [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] [ComImport] public interface IDispatch { [PreserveSig] int GetTypeInfoCount(out int info); [PreserveSig] int GetTypeInfo(int iTInfo, int lcid, out ComTypes.ITypeInfo ppTInfo); void GetIDsOfNames( [MarshalAs(UnmanagedType.LPStruct)] Guid iid, [MarshalAs(UnmanagedType.LPArray, ArraySubType = UnmanagedType.LPWStr)] string[] rgszNames, int cNames, int lcid, [Out, MarshalAs(UnmanagedType.LPArray, ArraySubType = UnmanagedType.I4)] int[] rgDispId); void Invoke( int dispIdMember, [MarshalAs(UnmanagedType.LPStruct)] Guid iid, int lcid, ComTypes.INVOKEKIND wFlags, [In, Out] [MarshalAs(UnmanagedType.LPArray)] ComTypes.DISPPARAMS[] paramArray, out object pVarResult, out ComTypes.EXCEPINFO pExcepInfo, out uint puArgErr); } [StructLayout(LayoutKind.Sequential)] public struct Variant { public ushort vt; ushort wReserved1; ushort wReserved2; ushort wReserved3; public IntPtr p; } } }

Are there languages that can't live without him?The tongues, in fact, before the lamp, this attribute. Languages are required by the API, which they rewrite, the CLSCompliant attribute they can use to remove warning during the compilation while attempting to use unsupported API. Maybe not. Reality is closer to the second option. In order to illustrate this, we'll create a pilot set to interact the low-level C# and high-level JScript. NET:using System; using System.Collections.Generic; using Microsoft.JScript; using System.CodeDom.Compiler; using System.Text; namespace ConsoleApp1 { class Program { static object JsExecute( string script, string[] refs, string func, params object[] args) { var jsc = new JScriptCodeProvider(); var parameters = new CompilerParameters( refs, "test.dll", true); parameters.GenerateExecutable = false; CompilerResults results = jsc.CompileAssemblyFromFile(parameters, new string[] { script }); if (results.Errors.Count > 0) { Console.WriteLine("Errors: "); foreach (var err in results.Errors) { Console.WriteLine(err.ToString()); } return null; } var ass = results.CompiledAssembly; var c = ass.GetType("C"); var f = c.GetMethod(func); return f.Invoke(null, args); } } } To make it work, you need to add a reference to Microsoft. JScript (and the project should be NET Framework - in NET Core no suitable type for integration with JS). In fact, the code takes the violin from the file, compiles and launches the reflection. I notice that results.Errors In addition to the mistakes, it also includes warnings, so we'll see what the compiler does. Now with his help, we can run the interesting API through JS and see how he'll lead himself.Pilot 1 - UInt32Let's just start by feeding the JS "non-compliant" UInt32:JS:class C { static function calc_sum(x, y) { return x + y; } } C#:static void Main(string[] args) { object res = JsExecute( "test.js", new[] { "mscorlib.dll", "System.Core.dll" }, "calc_sum", new object[] { (uint)1, (uint)2 }); Console.WriteLine(res); Console.Read(); } /* Вывод: 3 */ As you can see, everything worked out without mistakes. In fact, it doesn't prove anything, because JScript.NET, unlike Brauser equivalent, supports uint natically ( https://docs.microsoft.com/en-us/previous-versions/visualstudio/visual-studio-2010/ddacxdt5%28v%3dvs.100%29 ) But at least our experimental code is working.Experiment 2 - Microsoft.Extensions. ConfigurationWe'll see the Microsoft mentioned.Extensions. Configuration. Fortunately, it is compatible with the new versions of NET Framework. In order to verify this code on JS, which creates ConfigurationBuilder, defines the value in the Properties dictionary and tries to count it back:import Microsoft.Extensions.Configuration; class C { static function test() { var builder = new ConfigurationBuilder(); builder.Properties['key'] = 'Value'; return builder.Properties['key']; } } C#:static void Main(string[] args) { object res = JsExecute( "test.js", new[] { "mscorlib.dll", "System.Core.dll", "Microsoft.Extensions.Configuration.dll" }, "test", new object[] { }); Console.WriteLine(res); Console.Read(); } /* Вывод: Value */ Again, everything works fine. Well, there's nothing surprising, too, to put all types on the JS system.Pilot 3 - IndicatorsNow we take what JS really doesn't support - indexes. By the way, we can't even send a direct index, but there's an API like https://docs.microsoft.com/en-us/dotnet/api/system.reflection.pointer?view=netframework-4.5 .Box/Unbox, IntPtr, which allow the indexes to be rotated. And they, as you can guess, CLSCompliant(false). We'll write the code that passes the index in JS, and in the JS code, we'll try to work with it with the tools available to it:JS:import System; import System.Reflection; import System.Runtime.InteropServices; class C { static function write_value(p) { var ptr = new IntPtr(Pointer.Unbox(p)); Marshal.WriteInt32(ptr, 1); } } C#unsafe static void Main(string[] args) { int x = 0; Console.WriteLine("x before: "+x.ToString()); object res = JsExecute( "test.js", new[] { "mscorlib.dll", "System.Core.dll", "System.Runtime.dll" }, "write_value", new object[] { Pointer.Box(&x, typeof(int*))}); Console.WriteLine("x after: " + x.ToString()); Console.Read(); } /* Вывод: x before: 0 x after: 1 / Not only does there appear to be no warning of the use of 2 CLSCompliant(false) methods, but the code has successfully established the variable value of the indicator. The reason is that everything works under the hood, and JS never sees the need to create a direct variable-indicator. This does not mean that any API on indicators can be used in this way. If API accepts not void and allows byte*, it is no longer clear how to transform it.In short, the importance of CLSCompliantAttribute in the modern world is not so great. It needs more to shut down C# and individual FxCop analysers who fight in their absence than for the real integration of languages. Some decide to ignore the warning and not to place the attribute to save the amount of the binary. But if you just remove the attribute, it breaks the code that depends on it, which leads to a situation that doesn't even need to create, but not remove.
