Entity Framework v4 -> need some help with POCO's and Entities

Question

I'm using EF4 and I've got two entities that I wish to map to the same POCO. I'm not sure how I can do this.

Entity 1 → Foo (this represents a table FOO in the db)
POCO → Foo

Entity 2 → FooView (this represents a view FooView in the db)
POCO → Foo

I understand that I need to do something like

IObjectSet<Foo> _foos = CreateObjectSet<Foo>();

// Note spelling of the Entity.
IObjectSet<Foo> _foosView = CreateObjectSet<Foo>("FooViews"); 

But when i try this, it does compile, but it fails with the following exception:

System.ArgumentException: System.ArgumentException: The specified entity type, 'MyProject.Core.Foo', does not match the type 'EntityFramework.SqlServerModel.FoosView' from the EntitySet 'FoosViews'.

Any suggestions?

In NHibernate, one should solve this using Projections. So, I think that there must exists something similar like that in the Entity Framework. I've googled a bit, and I came accross this:
