TypeLoadException When Calling WinRT Component

Question

I have created C++ WinRT component that wraps DirectX. Then, I tried to access from my C# application and it gave me a TypeLoadException.

Answer 1

Hello,

Would you please provide us some same codes to reproduce this issue?

You can upload your project to
http://skydrive.live.com/

It is not necessary that you send out the whole of your project. We just need a simplest sample to reproduce the problem. You can remove any confidential information or business details from it.

Or you can try the way combing XAML and Direct X in this blog

Best regards,

Answer 2

Here is my project:

The MetroXna project is the winrt component and MetroXna.Tests is the C# application that throws a TypeLoadException

Answer 3

I think I may be having a similar problem (a Xaml app using a WinRT C# component throws a TypeLoadException that doesn't really make much sense). Was this ever resolved?

Answer 4

Nevermind. The problem was that I was using a namespace that didn't match the assembly name. That's not legal in WinRT, it seems. Problem solved!!
