Running docker run is not showing anything in console. Can you update "how to run" in readme?

Hmm... I don't think that I get your question right... but here is what you can try out in order having a difficulty running a container:

  1. Toggle output view and switch to 'OUTPUT' panel. It shows you the run-script's log, in our case it's the log of building an image and running spinning up a container with our app. something like the one below: _Killing all containers based on the docker.dotnet.debug image 7902e2b7e1e1 Building the image docker.dotnet.debug (debug). Sending build context to Docker daemon 6.656kB

  1. 'DEBUG CONSOLE' shows the log from the running app in the container _Starting: "docker" exec -i docker.dotnet.debug_1 /vsdbg/vsdbg --interpreter=vscode

    You may only use the Microsoft .NET Core Debugger (vsdbg) with Visual Studio Code, Visual Studio or Visual Studio for Mac software to help you develop and test your applications.

  2. And the last thing to try out is to look into log of the container itself. If everything was ok it should be empty, but if you have some issue with running a container it might contain some insights

run the following command:

docker logs docker.dotnet.debug_1
