hi all,
i am using ado.net entity data model for my application with MVC database first approach. Now the issue is that whenever i tried to update my entity model by following these steps
1 - right click on model designer
2- update model from database
3- Add tables
4- Finish

The new entity (table) comes on the designer screen but the entity doesn't comes in model.Or if just i updates any field and refresh the model the same behaviour occurs, it will update the designer not the originol entity. Then i have to delete the model and re-generate it from database then it works fine, but this is not the solution of my problem .
Kindly give me the solution ASAP.
thanks in advance.
