Visual Studio Xamarin android app crashes

Question

I'm trying to run an android xamarin app in Visual Studio 2013, it deploys normally, but crashes after start.

Here is the log:

The same thing on emulator with any platform and device.

Thank you in advance.

With the last Xamarin Update i run into this problem as well. Try disabling "Use shared runtime" in your Android Build options. It seems with the current Version a developent build is not able to call into the shared mono runtime.

What helped some others: Some suggested to just change "Target Version" (and "Compile Version" for VS) and Rebuild. The important part was to have changes in the Project File and not what exactly you changed "Target Version" from and to.
