I've got this message when try configure entityCollection in EntityCollection's Designer :

========================================== "Error Invoking "Set EntityFactory to use".Details = Unable to cast object of type = 'Northwind.DAL.HelperClasses.EntityCollection' to type =

'SD.LLBLgen.Pro.ORMSupportClasses.IEntityCollection2'. =

What's happen on this?

Please try recompiling the code before add the collection. Read this: http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=7560

SD.LLBLGen.Pro.ORMSupportClasses.NET20.dll ver 3.0.10.526

And @Daelmo How to see if the dll is correct version between Northwind.DAL and GUI?

The SD.LLBLGen.Pro.ORMSupportClasses.NET20.dll is suppossed to be referenced in both the of the projects, the gneerated DAL and your GUI application. You can open the properties of the reference in each project and check the version number, or make sure they are pointing to the same path.

(Edit) Please try to rebuild the entire solution. (DAL + GUI).

Please can you attach your failing code - we'll try and reproduce it here. We only need source files, not the binaries.

Thanks

Matt

Also, this sound like VS irregularity. What VS version are you using? Please install any missing service pack.

The project you attached, it's ok for me, I rebuild and I can view/edit the data controls in design view.

I tested with VS 9.0.30729.1 SP. Please update to the latest version. I will close this thread for now but please come back if you have any further questions/problems.
