Disable WPF.OpenGLControl

I am using the `SharpGL.WPF.OpenGLControl` in my app and some users are reporting it's failing to load when attempting to assign the shader program. While I try and track it down I'm attempting to disable the control with an app config setting. The problem I've got is that even if the control is disabled and hidden I get an exception as soon as the app is loaded. Is there any way to disable the control without having to remove it from the XAML?


Start by reproducing the WPF app-load failure with SharpGL.WPF.OpenGLControl present in XAML and disabled or hidden through app configuration. Trace when the control initializes and attempts shader assignment; done means the configured-disabled control remains in XAML without throwing during application startup.
