Container Debugging

You can attch Visual Studio 2022 to Linux Docker Container, then debug your application. Let's run Docker.

$ docker build -t blazorserverapp:dev -f src/Blazor/BlazorServerApp/Dockerfile .
$ docker run -p 8080:80 blazorserverapp:dev
warn: Microsoft.AspNetCore.DataProtection.Repositories.FileSystemXmlRepository[60]
      Storing keys in a directory '/root/.aspnet/DataProtection-Keys' that may not be persisted outside of the container. Protected data will be unavailable when container is destroyed.

$ docker ps

Open Visual Studio, Goto Debug > Attach to process.

Select Connection type: to Docker (Linux Container).

Select Find, Docker CLI host is Local Machine. Now your docker container is listed.

Select container and OK, then Attach.

Select Debug these code types to Managed (.NET Core for Unix), then OK.

Because Linux Docker source is differ from Windows source, you need to allow debugging source from different location. set Debugg Point and open Settings, enable Allow the source files to be different from origina.

Set debugger point and open http://localhost:8080/counter, click Increment button. Debugger stops at your point.
