[Ironpython-users] Run a WPF application written in IronPython on the client computer without the install IronPython

[Matt Ward]

If you use the /target:winexe with pyc.py it will add the STAThread
attribute to your main method. That should fix the exception.

In the C# console app you can add the STAThread attribute to the main method:

    class Program
    {
        [STAThread]
        static void Main(string[] args)
        {
