Creating new Microsoft.CodeAnalysis.CustomWorkspace

I try to create something like ConsoleClassifier in .NET Compiler Platform ("Roslyn") Samples. (Microsoft.CodeAnalysis v0.7...) At this point I get a ReflectionTypeLoadException:

CustomWorkspace workspace = new CustomWorkspace();

ReflectionTypeLoadException
{"Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."}
LoaderExceptions: FileNotFoundException
{"Could not load file or assembly 'Microsoft.Build, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. A rendszer nem találja a megadott fájlt.":"Microsoft.Build, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"}

What did I miss?

Is it possible to compile Roslyn against an older version of MSBuild?

You could compile Roslyn against an older version of MSBuild to avoid this problem. I've done this with VS 2012:

You need to install the VS "14" Build Tools package. You can find it in the ISO here.
