CoreRT compiled binaries not working #735

Hi guys,

I've been trying to come up with a basic web server using Suave + CoreRT. Check this repo for source code and error analysis. When I start the generated executable, it yields the following exception:

Unhandled Exception: System.ArgumentNullException: Value cannot be null. Parameter name: path1
   at System.IO.Path.Combine(String, String) + 0x53

@OshoNot I have pushed a new version 2.5.6 that fix the above exception.

Unfortunately it fails now further ahead on some printf usage. printf uses reflection which is problematic.

Exception:

Hi @ademar ,

This is actually a CoreRT directive, one need to use the rd.xml for reflection. I think this issue can be closed since once we add the rd.xml file, everything runs ok.
