Test case showing problem with Reflection invoke on method with out parameter

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.11)
Gecko/2009060308 Ubuntu/9.04 (jaunty) Firefox/3.0.11

I have a method defined like:
private DateTime GetLastRunInfoForCheck(Guid checkId, out string[] bookChkInfo)

When I attempt to invoke it with reflection It throws a MissingMethodExp.

If I remove the out param it works as expected.

The attached test case works in .NET.


Reproducible: Always

Steps to Reproduce:
1. compile and run Test program
2.
3.
Actual Results:  
MissingMethodExp 2

Unhandled Exception: System.MissingMethodException: The best match for method
GetLastRunInfoForCheck has some invalid parameter.
