EF4 - Is it possible to add a property to an entity which won't be reflected in the db?

Question

In the epic quest of me getting my Create and Edit methods working for my complex model, I've come up with an idea - adding a boolean IsSelected property to one of my entity classes for use with checkboxes in my views. Is it possible? Would something as simple as

public partial class Platform : SomeBaseClass
{
    public bool IsSelected { get; set; }
}

Do the trick?

Yes, it works. Have you tried it?

That said, I recommend dedicated view models.

Haven't had a chance to try it as I'm away from my dev computer. I just figured it was the easiest way to solve my problem here: http://stackoverflow.com/questions/4196247/mvc2-model-binding-w-many-to-many-at-the-cusp Unless you have a better/cleaner solution. – Major Productions Nov 16 '10 at 20:23
I agree with stuntz, instead of putting isselected in the entity make a platformitemviewmodel and wrap your entity in that with an extra isselected property. this will keep your model cleaner. – dnndeveloper Nov 17 '10 at 02:21
