EntityFramework Get object by ID?

Question

Is it possible with Generics to get an object from my EntityFramework without knowing the type?

I\'m thinking of something along the lines of:

public

Here's the method I use to get an Entity object by ID.

public TEntity GetByKey(object keyValue) where TEntity : class
    {            
        EntityKey key = GetEntityKey(keyValue);

        object originalItem;
        if (ObjectContext.TryGetObjectByKey(key, out originalItem))
        {
            return (TEntity)originalItem;
        }
        return default(TEntity);
    }

You may find this a more robust solution than some of those provided above. I've used it as part of a generic repository in a lot of projects. Hope it helps you out.
