Visual Studio regularly throwing exception - visual-studio

Question

Visual Studio 2015 is regularly becoming odd.
Keys typed are appearing in semi-random orders, I'll sometimes have to press keys twice or more.
I think this seems to be around key words, rather than variable names or literals.
After about five minutes I'll get the error dialogue telling me that there was an exception that might be caused by an extension.
The entry in ActivityLog.xml is below:
<entry>
<record>762</record>
<time>2015/08/11 20:17:02.056</time>
<type>Error</type>

What's going on? How can I fix or further diagnose this?

Uninstalling NCrunch didn't solve anything
Uninstallong both NCrunch and Resharper 9 seems to have fixed it.
Reinstalling Resharper only seems to be OK.
I have reinstalled NCrunch after
I haven't tried reinstalling NCrunch yet a month and so far everything seems OK.

Answer 1

I've been having this issue just with Resharper (9.1.X).
I referenced this thread in my uninstall. I got an email from support to try some release candidates for 9.2. As long as 9.2 hasn't had an official release, it may be worth your time to try them if you are willing to take on a small risk.
https://confluence.jetbrains.com/display/ReSharper/ReSharper+9.2+EAP
I'm starting to try RC3, I'll come back to edit in my experience later. I figure it's probably better to get a possible solution up sooner rather than later, no matter what my experience with it dictates.
They just released Resharper 9.2. I'd see if installing that fixes the issue.
Alternatively, this answer helped solve the problem for me personally in case the new version doesn't solve the issues.

Answer 2

potential problem - NCrunch extension has some issues currently sometimes in VS 2015. It is not currently behaving properly for .NET 4.6 according to this blog: http://blog.ncrunch.net/post/License-Server-Introduced!-NCrunch-216-now-available.aspx
