Code Contracts crashing in background in VS2015

[JamesFaix]

Edit: Sorry, this is the same issue as #441

Hi Sergey,

There are several different issues I am currently experiencing with Code Contracts in VS2015.

The post I made on StackOverflow (http://stackoverflow.com/questions/38103495/vs2015-crashing-with-a-new-guard-page-when-just-editing-source-code) was the latest, and it seems to have stopped since upgrading to CC v1.10 RC2, but it could be just a coincidence.

Another issue I've been having is Code Contracts crashing in the background when I believe Roslyn is doing incremental compilation. This will not crash VS2015, but will prompt me to submit a bug to Code Contracts. This may be an issue with Code Contracts Editor Extensions. I am not sure if this is the right place for those issues. Here is the failure from the Output window:

Thanks a lot for bug report. I'll take a look at it.
