MSBuildWorkspace.Create on mono throws ReflectionTypeLoadException

The following works on vanilla .NET but throws a ReflectionTypeLoadException when I try to run it through mono:

var props = new Dictionary<string, string>();
props["CheckForSystemRuntimeDependency"] = "true";
using (var msWorkspace = MSBuildWorkspace.Create(props))
{
   ...

Exception is:

System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded.

Is this a known problem?
