Hello all,

I'm testing a demo application with nhibernate and I'm found problems, already search in documentation but don't found. My test is such as bellow:

1. I has a IObject interface in myFramework.ddl.
2. I create a new class library for my business objects, myBO.dll.
3. I create the People class that implements the IObject in myBO.dll.
4. In myBO.dll I create the mapping files with embebed resources.
5. I create a new application (in the reallity a class library to NUnit) that use myBO.dll and has the code to work with NUnit (configuration, sessions and etc..).

The problem is raised when I execute the Configuration.BuildSessionFactory method, I get the exception:

-----------------------------------------------------------------------------
A first chance exception of type 'System.InvalidOperationException' occurred in nhibernate.dll

Additional information: Referenced class 'myBO.People' has base class or interface 'myFramework.Persistence.IObject' defined in an assembly that is not referenced. You must add a reference to assembly 'myFramework'.
-----------------------------------------------------------------------------

Anybody can help me, anybody know how solve it!?


Thank's.....

Hi FernandoVM,

The exception is actually telling you exactly what you need to do. Your application has a reference to your myBO.dll but since myBO.dll exposes the People class which is implements an interface defined another assembly (myFramework.dll) you must add a reference to that assembly.

If you're using VS.Net then right click on the References folder in the Solution Explorer, select Add Reference and add a reference to your myFramework.dll.

Hope that helps,

Symon.

Hi Symon,

Thank's by your attention. The problem is it, both my application and myBO.dll already has a reference to myFramework.dll. Observe that exception is raised in NHibernate, not in my application, see:

A first chance exception of type 'System.InvalidOperationException' occurred in nhibernate.dll.

:(

And now, what I can do!?
Any help will be welcome!

Thank's..

Hmmm. Sorry about that FerdinandoVM - I guess I misunderstood the issue at hand!

I'm not sure if it will help, but maybe adding the myFramework assembly using the AddAssembly method of the Configuration object might work?

Or importing the IObject interface using the AddImport method of the Mappings object returned by the CreateMappings method of the Configuration object?

eg:



Don't know if either of these will work - just suggestions.

Cheers,

No problem.. :)

Thank's again by your attention.

I already try it, I add the bellow lines in myBO.dll:



and try this also:




:?

And now, more any idea??

Thank's...

Sorry - that's my bag of tricks emptied. Anyone else got any bright ideas?

Try to isolate the problem as much as possible...

You may even build a "fake" solution with fake interfaces/classes to reproduce the problem.
If you succeed and build a fix that should be applied to NHibernate, then post the TestCase (NUnit :) ) and the patch in a new JIRA issue (http://jira.nhibernate.org/).
