I get build failures on my projects with the following exception:

I have disabled FIPS in VS2012 in the devenv.exe.config file with <enforceFIPSPolicy enabled="false"/>
as well as disabling it in Windows via HKLM\System\CurrentControlSet\Control\Lsa\FIPSAlgorithmPolicy\Enabled

Anyone with some info on this?

Thanks!

Adding the FIPS disabling code in the C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Remco Software\NCrunch for Visual Studio 2012 .config files (all of them) did not help.

However the machine.config did the trick!

Thanks!
