Grpc-dotnet: Deploy .NET Core with Grpc on Docker get Error.

[vuggg]

I'm build a web API app using .NET core and gRPC for Csharp.

In Local, It work verry well, but when I build container and run it on Docker Desktop, receive:

docker logs --tail=100 f30a5c0d755e

@vuggg What packages are you using? It looks like you're using grpc core (and the issue should be moved to https://github.com/grpc/grpc). What packages are in your project?
