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

You can create a new ApplicationContext to represent multiple forms:

public class MultiFormContext : ApplicationContext
{
    private int openForms;
    public MultiFormContext(params Form[] forms)
    {
        openForms = forms.Length;

        foreach (var form in forms)
        {
            form.FormClosed += (s, args) =>
            {
                //When we have closed the last of the "starting" forms, 
                //end the program.
                if (Interlocked.Decrement(ref openForms) == 0)
                    ExitThread();
            };

            form.Show();
        }
    }
}

Using that you can now write:

Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new MultiFormContext(new Form1(), new Form2()));
