Run two winform windows simultaneously

Question

I have two C# winform (.NET 4.0) forms that each run separate but similar automated tasks continuously. Separate in that they are distinct processes/workflows, but similar

Answer 1

If you really need two windows/forms to run on two separate UI threads, you could do something like this:

static class Program
{
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        var thread = new Thread(ThreadStart);
        // allow UI with ApartmentState.STA though [STAThread] above should give that to you
        thread.TrySetApartmentState(ApartmentState.STA); 
        thread.Start(); 

        Application.Run(new frmOne());
    }

    private static void ThreadStart()
    {
        Application.Run(new frmTwo()); // <-- other form started on its own UI thread
    }
}
