    Hi Telerik Friends, I'm currently having trouble while developing a web part for Microsoft Office Sharepoint Server 2007, my target is to retrieve data from a sql server database. I have already created a C# class library project and enabled ORM, this includes persistent classes and Data access code, I have also completed the reverse mapping wizard so my table and objectscopeprovider classes have been created. I embedded app.config and reversemapping.config files into the assembly to be my Data layer dll. Then I have created a Sharepoint solution project, it contains a feature with a web part which loads a web user control. I add a reference to my data layer dll in the solution deploy project and inside my web user control trough register, but i'm getting the next error:

    The ObjectContextProvider named 'DataLayer.ObjectScopeProvider1, DataLayer' could not be resolved.

    I hope someone of you could help me

    Hello David,

    that looks like the DataLayer assembly is not being able to get loaded. Is that a versioning problem?
    What I would do in such a scenario is to include a hard reference to one of the types in the assembly from the referencing thing; a System.GC.KeepAlive(typeof(DataLayer.ObjectScopeProvider1)) should do the trick.
    That informs all participants that this referenced assembly is really needed.
