your workstation has fips policy enabled in windows cause number of encryption , hashing algorithms fail if they're used. it's prevent insecure encryption used in banking , military environments. unfortunately seems breaks msbuild when building visual basic (and there known issues xaml too).

to solve issue need edit msbuild.exe.config version of msbuild you're invoking (probably 1 in %programfiles(x86)%\msbuild\14.0\bin).

add:

<configuration>      <runtime>      ...         <!-- below tag disable security policy checking fips -->         <enforcefipspolicy enabled="false"/>      ...     </runtime> </configuration> 

for more information on impact of fips, read kb article effects.

you may need same thing devenv.exe.config, can found in %devenvdir% on visual studio command prompt version you're having issues with.
