Hello Everyone , I am able to instrument my app i.e. on dotnet app . I was setting env variable in cmd and running the command in powershell so my app was not able to capture the env variable. I resolved by configuring env variable in cmd ```auto set ELASTIC_APM_SERVER_URL=http://192.168.1.7:8200 set ELASTIC_APM_SECRET_TOKEN=Wm8ENthMVqcCti1Voh8uz2Pi set ELASTIC_APM_SERVICE_NAME=DOT_NET_APP ``` then i run the command `dotnet run` in same cmd shell. In the final i got the desired result.
