Vs update result in System.TypeLoadException

I am developping a windows phone 8.1 sdk
When I use vs 2013 update 3,the code works and i can run my demo.
but,yesterday,I update my vs 2013 to update 4,then throw a System.TypeLoadException
code details below: 

var swapChainPanel = new SwapChainPanel();
Children.Add(swapChainPanel);
var res = new CXMapResource("", "");
cxEngine = new CXMapEngine(res);

Type CXMapResource is a windows runtime component type written by c++
and it is the first winrt type I load in my code
I set a break point before this line,it goes here,and then continue,then crash,
output:

A first chance exception of type 'System.TypeLoadException' occurred in Com.AMap.winmd
A first chance exception of type 'System.Exception' occurred in WP8.1Demo.ni.EXE

VS 2013 UPDATE5 CTP2

Solution

  • Unfortunately we have the same problem with Update 4, this is probaly caused by referencing a winmd (C++) component. We have the problem with the SmoothStreaming SDK for Windows 8.1.

    We have reached to Microsoft but no answer yet.

    A colleague solved this problem by reinstalling Windows and Visual Studio. Then he updated to Update 3. (Just removing the update 4 didn't work for him) I rather avoid this 'solution' but if there is no hotfix next week, I probaly have to do these steps.

    Update

    Microsoft answered my issue that they will fix this problem in Update 5. https://connect.microsoft.com/VisualStudio/Feedback/Details/1036072
