Xamarin，Grpc，无法使用令牌0100002b解析类型

我正在努力让gRPC与Xamarin合作。

我知道您可能认为这是重复的问题，因为有关该错误的stackoverflow上存在类似的问题，但我尝试合并所有引用和nuget包，尝试清理项目并重建。

我在Windows 7和Windows 10上尝试了Xamarin.Forms，Xamarin Android项目。所有这些项目都有相同的错误。排队异常：

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)"

输出：

希望有人能帮助我。提前谢谢！

请注意，gRPC C＃目前还没有官方支持   对于Xamarin（我们使用的是本机C库和核心RPC   功能并通过P / Invoke调用它 - 我认为可能是   您可能会看到的问题的根本原因。可以制作gRPC C＃   为Xamarin工作，但它需要构建正确的版本   手动构建grpc_csharp_ext.dll本机库（可能还有   还有一些调整）。
