[DotGNU]What's this error?

[DrDiettrich]

During my first steps with pnet on Windows I get this error:

$ ilrun test
App::Test [2096] - call at verify_call.c:1088
token 0x0A00002C: member `System.Collections.DictionaryEntry..ctor' not
found
token 0x0A000038: member `System.Threading.Monitor.Enter' not found

`System.Collections.IDictionaryEnumerator.get_Key' not
found
Hashtable::.cctor [30508] - call at verify_call.c:1088
Uncaught exception: System.Security.VerificationException

How to interpret these lines?

The reason for this error is not clear. It occurs with quite simple
code, but I cannot trace it down to a single condition. Multiple but not
all of the following conditions can cause this error to appear:
- call to a (static) procedure
- adding strings ("test" + msg)
- Console.WriteLine

References to the mentioned classes are not required, so it might be an
error in Hashtable, which is called from inside the runtime system?
