After loading a VS2013 C# project in VS2015 I got the dreaded MSB3884 warning (Could not find rule set file). A little annoying since I wasn’t knowingly using code analysis (but I might now).

Here’s what I did to fix the warning:

1. On the project properties go to the Code Analysis section.
2. Select the Browse option on the list of rule sets:
   
3. Browse to the VS2015 rule sets folder:
   C:\Program Files (x86)\Microsoft Visual Studio 14.0\Team Tools\Static Analysis Tools\Rule Sets
4. Pick a rule set.. the default used by new projects is:
   MinimumRecommendedRules.ruleset
5. The new rule set is applied:
   

Then rebuild – problems gone !

 

 

My shared folder drive mapping no longer worked after the November update of Windows 10.

To fix this I had to manually uninstall VMWare Tools, reboot, then install and reboot again. (Using the Reinstall option from the menu didn’t appear to fix the problem).
