Random helpers for Windows Forms apps. .NET Core only for right now.

OnError

For use in event handlers which are "async void".

await OnError.ShowMessageBox(async () => {
  // do stuff
});

ExitWhenFormsClose

In a Windows Forms app, Application.Run(...) handles plumbing window messages on your UI thread. The default app template calls
Application.Run(form1) which causes this thread to exit when that specific form is closed. But what if you want to have multiple windows and you want the process to exit when all windows are closed, or when specific ones are closed? That is what this is for.

See the class comments for details on how to use it.
