Here is the case:

I have an existing project created using entity framework. Now I have to create a new form and save its data to a new table using enterprise library. But the catch is that I have to do it without refreshing the existing edmx of the project. When I am calling the insert query, its showing the error:

The type Database cannot be constructed. You must configure the container to supply this value.
Kindly help.
