Visual Studio 2013 crashes when writing opening angle bracket

Question

everytime I try to write an opening angle bracket in vs13 it crashes.

The Problem only happens in a xamarin.forms project and in an xaml-file. Every other key works fine, just the opening angle bracket causes the problem. If I copy/paste it in the code it works fine, as well... but this can't be the solution...

Version: VS Premium 2013 - 12.0.31101.00 Update 4

I am using Xamarin for Visual Studio Version: 3.11.586 and XAML Styler in version: 1.5.

Answer 1

Problem solved by deleting the hidden file .suo in the projectdir. After a restart everything works fine! :)
