Hi VS 11 Team:
I have to open a new thread to report the following issue, which has been reported earlier in a thread (http://connect.microsoft.com/VisualStudio/feedback/details/722313/vs11-build-with-8175-will-not-allow-the-creation-of-c-static-lib-that-calls-winrt-apis) but that thread has been already closed.

It looks like the bug is still in the VS 11 Beta. 
When we build a static library with WinRT calls in the source code, the compiler still gives error message "error LNK1326: archiving OBJ compiled with /ZW into static lib is not supported".

Is there a work around for this?

Thanks, YongKang. Putting /force:allowzwobj to Librarian part of Command Line works perfectly. However, only adding that to a newly created Metro style static library isn't enough.

First of all, in Configuration Properties -> General, "Metro Style App Support" still can't be turned on, but the C/C++ -> General one can. However, even with that, Debug part of Code Generation -> Enable Minimal Rebuild still needs to be turned off manually. Lastly, these lines need to be added to C/C++'s Command Line part:

/FU Platform.winmd /FU Windows.winmd /AI "C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\vcpackages" /AI "$(WindowsSDK_MetadataPath)"

I hope these manual changes won't be necessary in the next release.

We have fixed this issue and the fix will be included in the major release of VS 11. With VS 11 Beta, the workaround is to add /force:allowzwobj onto the command line.

Thanks again for your feedback.
