博客详细描述了在使用基于.Net Framework的程序中遇到的gRPC连接问题，特别是Grpc.Core版本1.4.1时出现的自动连接失败与错误提示。作者尝试重新调用以解决此问题，并建议升级到gRPC新版本1.12.0来尝试修复。

1.问题还原：

The service does not automatically connect, free after a period of time, the first call will appear the following error, next to normal.

The program is based on.Net Framework, The Grpc.Core version is 1.4.1.

Grpc.Core.RpcException: Status(StatusCode=Unavailable, Detail="Endpoint read failed")
   在 System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)
   在 System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
   在 Grpc.Core.Internal.AsyncCall`2.UnaryCall(TRequest msg)
   在 Grpc.Core.Calls.BlockingUnaryCall[TRequest,TResponse](CallInvocationDetails`2 call, TRequest req)
   在 Grpc.Core.DefaultCallInvoker.BlockingUnaryCall[TRequest,TResponse](Method`2 method, String host, CallOptions options, TRequest request)
   在 Grpc.Core.Internal.InterceptingCallInvoker.BlockingUnaryCall[TRequest,TResponse](Method`2 method, String host, CallOptions options, TRequest request)

The document says I can try again. Isn't this supposed to be implemented internally in grpc.core?

使用新版本试试：This issue looks stale and it is not clear what the intent was. Also 1.4.1 is pretty old, feel free to try with 1.12.0 and if you are still seeing a problem, file this as a new issue.
