Xamarin，Grpc，无法解析令牌为0100002b的类型

问题描述

我正在尝试使gRPC与Xamarin一起使用.

I am trying to get gRPC working with Xamarin.

我知道您可能认为这是重复的问题，导致关于该错误的stackoverflow上存在类似的问题，但是我尝试合并所有引用和nuget包，尝试清理项目并重建.

I know you may think that it is duplicated issue, cause there are similar questions on stackoverflow regarding that error, but I have tried consolidate all references and nuget packages, tried clean project and rebuild.

我在Windows 7和Windows 10上尝试过Xamarin.Forms，Xamarin Android项目.它们都具有相同的错误.取得异常:

I have tried Xamarin.Forms, Xamarin Android projects on Windows 7 and Windows 10. All of them have the same error. Getting exception in line:

Channel channel = new Channel(ip, port, ChannelCredentials.Insecure);

例外:

"Could not resolve type with token 0100002b (from typeref, class/assembly System.Runtime.Loader.AssemblyLoadContext, System.Runtime.Loader, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a)"
