Workaround: dotnet run under Linux X64, then scp the grpc project folder to Loongson machine:

[loongson@localhost HelloGRPC]$ ~/zhaixiang/to_ship_sdk/dotnet bin/Debug/netcoreapp3.1/HelloGRPC.dll --urls http://10.2.5.91:5001
info: Microsoft.Hosting.Lifetime[0]
      Now listening on: http://10.2.5.91:5001
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Production

      Content root path: /home/loongson/zhaixiang/HelloGRPC

Thanks,
