I got this error:
rsUnexpectedCompilerError: An unexpected error occurred while compiling expressions. Native compiler return value: ‘-1073741511’<
In order to resolve the RDLC build problem I had to do the following (lots of digging):
https://support.microsoft.com/en-us/kb/3118750 Resolution for scenario 2 Customers have to uninstall updates 3098779 and 3097997 if they have upgraded their systems to the .NET Framework 4.6 or have installed Visual Studio 2015 from a fully updated .NET 4.5.1 or 4.5.2 system that has updates 3098779 and 3097997 installed.
Rebooted and it worked.
