NotSupportedException thrown in NR CecilLoader when using "Debug executable"

[siegfriedpammer]

Steps to reproduce:

1. download and install RSSBandit http://rssbandit.org/download/rss-bandit-download/
2. launch SD and select "Debug > Debug executable" from the main menu
3. Select RSSBandit.exe and run it
   4.SD will automatically stop at the first instruction in Program.Main, so just click continue

expected result: RSSBandit.exe is launched completely and can be debugged

actual result: right after continuing execution, SharpDevelop fails with the following exception. The only solution is to terminate SD.
