Signoz + OpenTelemetry Auto Instruments with Dotnet

[hoesein]

Hello everyone 👋

I'm using Signoz from docker-compose following base on their document and it up and running. And my plan is to use that service from my dotnet application which also running in docker.

Problem is no service, log, metrics were found in Signoz UI even though all services are running well. Let me drop my Dockerfile and docker-compose file in here.
