Running Xamarin studio on windows 8.
In debugging an application that runs OpenGL via openTK I occasionally get the following error:
Error HRESULT EFAIL has been returned from a call to a COM component.
System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.

Make sure that you are building a 32bit exe. 64bit exes are not supported when using the Microsoft .NET runtime.
Your other option is to install the Mono runtime and target that for debugging.
The project is already 32bit.
Swapping to 64bit gives a slightly different error message: System.Runtime.InteropServices.COMException (0x80070032)
Additionally, the dialog seems to eventually causes weirdness if left open.
Basically, it pops under the main window and vanishes leaving the main window unusable until it is closed, which is hard to do as it is behind the main window.
I would recommend that you use the Mono runtime for debugging. The Soft Debugger backend is lightyears ahead of the CorDebugger backend.
Cool, will install mono and go from there.
Thanks for the help.
