Debugging Libraries with Visual Studio Code

• Install Visual Studio Code
• Install the C# Extension
• Open the folder containing the source you want to debug in VS Code - i.e., if you are debugging a test failure in System.Net.Sockets, open runtime/src/libraries/System.Net.Sockets
• Open the debug window: ctrl-shift-D or click on the button on the left
• Click the gear button at the top to create a launch configuration, select .NET Core from the selection dropdown
• In the .NET Core Launch (console) configuration do the following
  • delete the preLaunchTask property
  • set program to the full path to dotnet in the artifacts/bin/testhost directory.
    • something like artifacts/bin/testhost/netcoreapp-{OS}-{Configuration}-{Architecture}, plus the full path to your dotnet/runtime directory.
  • set cwd to the test bin directory.
    • using the System.Net.Sockets example, it should be something like artifacts/bin/System.Net.Sockets.Tests/netcoreapp-{OS}-{Configuration}-{Architecture}, plus the full path to your dotnet/runtime directory.
  • set args to the command line arguments to pass to the test
    • something like: [ "exec", "--runtimeconfig", "{TestProjectName}.runtimeconfig.json", "xunit.console.dll", "{TestProjectName}.dll", "-notrait", ... ], where TestProjectName would be System.Net.Sockets.Tests
    • to run a specific test, you can append something like: [ "method", "System.Net.Sockets.Tests.{ClassName}.{TestMethodName}", ...]
• Set a breakpoint and launch the debugger, inspecting variables and call stacks will now work
