Common Language Runtime detected an invalid program.

What a wonderfull exception, wow..
[System.InvalidProgramException] = {"Common Language Runtime detected an invalid program."}

I guess having a relatie business object being inherited by a person business object is the problem.. while using just 1 smart-factory which knows uses typeof() the generic type.

Does anyone has an idea what i do wrong? Please reply if u have a suggestion or have an idea.. or even if u don't know either hehe. Just such a strange exception!

The MethodCaller.CallMethod dynamic method stuff just doesn't know anymore.

try
{
result = methodHandle.DynamicMethod(obj, inParams);
}
catch (Exception ex)


obj --> {U4A.Ceedrie.Data.Relatiemanagement.Factory.RelatieFactory}

inParams --> {Csla.SingleCriteria}


Persoon business object

[CslaFactory("Factory Type=U4A.Ceedrie.Data.Relatiemanagement.Factory.RelatieFactory, Data.Relatiemanagement;Item Type=U4A.Ceedrie.Business.Relatiemanagement.Persoon, Business.Relatiemanagement")]
public class Persoon : Relatie
...

Relatie business object

[CslaFactory("Factory Type=U4A.Ceedrie.Data.Relatiemanagement.Factory.RelatieFactory, Data.Relatiemanagement;Item Type=U4A.Ceedrie.Business.Relatiemanagement.Relatie, Business.Relatiemanagement")]
public class Relatie : U4ABusinessBase>
...

RelatieFactory : ObjectFactory

implimenting a method

public Business.Relatiemanagement.Relatie Fetch(SingleCriteria, int> criteria)
{
...

hmmm... the generic brackets aren't visible in my post, i guess the forum sees them as specials?

I managed to find that it's the signature in the ObjectFactory being the cause of this InvalidProgramException. It seems that the signature cannot contain a generic, if it does then it doesn't say "Method not found", but it just gives this InvalidProgramException. Maybe that the dynamic method implimentation isn't perfect yet? Maybe someone want to take a look at the implimentation in Methodcaller.cs? Greetings, Raymond de Jong

Can this 'bug' or 'wish' be added into the bugtracker system?

The exception you're getting is usually caused by a bug in the compiler.  Can you post a small complete sample that reproduces the issue?

i'll try and create a small sample when i'm back at work
