Hi tersiusk,
 
Upon what operation are you getting the exception?
Are you using an injected base type? (you can do that in your model properties)
Can you upload a small sample (against northwindIB) reproducing the issue?

I want a generic class to do some type safe methods etc. For instance I want all my entities to have a GetAll method which need to return ObservableCollection<T>. ]]> Mon, 08 Nov 2010 08:48:14 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=2284&PID=9035#9035 Generic Base Class for entities : Why exactly do you need a Generic... http://www.ideablade.com/forum/forum_posts.asp?TID=2284&PID=9034#9034 Author: smi-mark

Why exactly do you need a Generic class?

When you have a base class EntityBase, User will inherit from EntityBase. You do not need to make it Generic

Hi

I have created a generic base class for my entities but I'm running into some issues with the serialization. I have defined the generic class as below. 
public abstract class EntityBase<T> : EntityBase
{      
}
I'm getting Error:
while getting known types for Type 'NetstarSecurity.DevForce.Model.EntityBase`1[T]'. The type must not be an open or partial generic class.
Now obviously my basetype is a open generic class...
I have tried adding the [KnownType(typeof(EntityBase<User>))] attribute but it still gives the same error. 

Please help. :)
