I have a C++/Cx component which I use in a C# DirectX Metro app.
It worked fine.
until my latest innocuous changes.. where my C# project can't use the C++/Cx project anymore, I got this error:
"There was a problem reading metadata from 'C:\Dev\WinRTDirectXSamples\Debug\DXBase\DXBase.winmd' ('An attempt was made to load a program with an incorrect format.')."

Reverting the changes made it work
(only a few properties / method in the C++ component changed, i.e. no project - target architecture changes)

Details (expand)

Visual Studio 2012

I got a sample there (VS2012bug.zip):
https://skydrive.live.com/redir?resid=7E5D519CDA2F47D0!1917

It's a Mercurial (HG) repository.
Revision 16 compiles and run fine, revision 17 doesn't.

Revision can be changed with TortoiseHG workbench:

The solution doesn't compile, I got an error about a corrupted .winmd

The solution should compile, or the C++ component should not compile and have an error message explaining what's wrong.

Hi lloyd, thanks for submitting feedback on Visual Studio and .Net Framework. We'll close this issue because you have found a workaround. Thanks for your time.

I found a weird work around:

On a wild hunch (it's a compiler problem, right? I though I'll try to help it)
There was 2 properties in DXContext defined with a macro (TargetType, Status), I got rid of the macro and used code instead and then it worked fine!
