Example code showing invoking method via reflection which has COM object as
param

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

Attach a test program as example (which doesn't have COM object dependency
included)

For example:

class MyClass
{
 public string MyMethod(MyCplusplusCOMObject o)
 {
  return "hello world";
 }
}

Essentially if I attempt to call MyMethod via reflection I get a
MissingMethodException

Changing parameter type MyCplusplusCOMObject to object causes things to work.

Reproducible: Always

Steps to Reproduce:
1.
2.
3.
Actual Results:  
MissingMethodExp 2

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

/home/hindlet/ReflectTest/ReflectTest/Main.cs:37 

Expected Results:  
hello world
