Hello,
 
I started a new cocktail development on an existing SQL Server database.
Everything looks ok, but i wondered what to do with the Validate in EntityManagerDelegate.
In the Code First this calls the Virtual Validate in the EntityBase, but for my solutions my entities are generated from the EntityModel. What is the best way to do this. Add an interface in my partial class for the entities: IEntityBase?
I suppose you do want to add some extra validation there.

You can still add a base class as documented here and do it similar to how it's done with code first.

When i introduce the Entitybase injection it generates OK, but when i build the following errors is reported.
 
Error 27 An error occurred during metadata generation and a metadata file could not be created.  Error: Unable to find the requested .Net Framework Data Provider.  It may not be installed. C:\Users\JKT\Documents\Visual Studio 2010\Projects\AccoBooking\packages\IdeaBlade.DevForce-2010.Aop.6.1.9
\tools\IdeaBlade.DevForce.Common.targets 110 5 DomainModel
When I remove the injected EntityBase the error disappears. I don't understand this.

You appear to have the DevForce 2010 Code-First NuGet package installed to your project. Since your model is not code-first you should uninstall the Code-First package.

Yes forgot about that DevForce CF link. Thanks Marcel!
