After install Visual Studio 2015 community and NUnit Test Adapter, I cannot find test cases in the test explorer.
Cause
As test projects are stored on a network driver E, the test explorer need authorization to access these projects.
Solution
Run the command:
%windir%\Microsoft.NET\Framework\v4.0.30319\CasPol -m -ag 1.2 -url file://E:/* FullTrust
SETX COMPLUS_LoadFromRemoteSources 1 /M
Echo Please restart your Visual Sutdio...
