DbContext is a lightweight version of the ObjectContext class, which is laid almost right on top of ObjectContext (there is even a way to get to the ObjectContext from just the DbContext). It's also a lot easier to use, IMO, and makes CRUD operations a sinch.

Hi Mahesh ,
DbContext build up on ObjectContext,with this they have reduced lot of extra noise that ObjectContext had.
But you can anytime convert it back to ObjectContext when you find dbContext doesn't meet what you required.

Basically on the ObjectContext, when you do dot (.), everything is just right there which makes the list pretty huge.
What the EF team actually wanted to expose on DbContext are entities which are only specific to your domain and rest of ability of the framework is tucked in under different properties.
It just makes the programming experience easier.

* Please accept this answer if it works for you.

DbContext is just a wrapper around ObjectContext
DbContext is just a set of APIs that are easier to use than the APIs exposed by ObjectContext
Anyway here there is a very simple VS Template that uses Repository Pattern and EF
