Can anyone help me?

The nameof operator is a new feature in C# 6 which is the default C# language version in Visual Studio 2015.

Make sure that you are using the correct version of MSBuild. This is the version that ships with Visual Studio 2015:
C:\Program Files (x86)\MSBuild\14.0\Bin\MsBuild.exe.

nameof() is not a part of the .NET Framework. But of the C# 6.0 langauge definition.

So with wich C# language version is the compiler running?

Sorry for delay... you are right, I was using the wrong msbuild version.

Thanks,
