OK, it works, but is a hack.:) Requires UnmanagedCode permission, creates a
new process, it is slow, the output has to be interpreted, ...

It's true, that the functionality that is implemented in the runtime and is
called by assemblies using InternalCall cannot be used on other runtimes.
I recommend detecting runtime type using internal classes in mscorlib.dll
because non InternalCall methods outside mscorlib.dll can simple be used on
other runtimes and public classes that are specific for a runtime can be
implemented by other runtimes even if the assembly cannot be simply copied
to provide compatibility with other runtimes. Using internal classes is good
because it's very unlikely to use two class library the same internal class.
And if it has specific name like MonoType you can make sure that the name it
won't be used by other runtimes.
