Generating native code with Grpc.Core

[DenMpei]

Good day!

I hit the following issue:
dotnet publish -r win-x64 leads to numerous compilation errors

Inside the package is used Grpc.Core 2.28.1

Сompile with Microsoft.DotNet.ILCompiler 1.0.0-alpha-29408-02

Adding code from this issue doesn't help

I ask to give advice to solve the problem.
Regards.

The attribute got renamed to UnmanagedCallersOnly. Try this definition:

corert/samples/NativeLibrary/UnmanagedCallersOnly.cs

Lines 6 to 12 in 4ce1c21

 [AttributeUsage(AttributeTargets.Method)] 
 public sealed class UnmanagedCallersOnlyAttribute : Attribute 
 { 
     public string EntryPoint; 
     public CallingConvention CallingConvention; 
     public UnmanagedCallersOnlyAttribute() { } 
 }

Didn't work :( I will try to provide a minimal version of the project. But it won't be soon, because reference on Grpc.Core is very deep in real project. :(

Make sure you put the UnmanagedCallersOnlyAttribute-annotated method in the entrypoint assembly (whatever assembly is the main executable). The compiler doesn't look elsewhere.
