If a call Instruction's Operand is a GenericInstanceMethod how do you
find the MethodDefinition of what it's calling?
I'm looking for:
System.Void CecilTest.GenClass`1::GenMethod(U)
But my call is made as:
System.Void CecilTest.GenClass`1<GenType>::GenMethod<System.Object>(!!
0)
How would I draw the dots between the two?
Regards,
Ivan
