How to applying Store Procedures to build Entity Framework in ASP.Net MVC project

After you have successfully build your Entity Framework, you can update it if your tables or store procedures have been changed. Right click on the Entity Framework model in your solution explorer, choose Open, and click on Model Browser. Then right click on the root node of the model, and choose Update Model from Database, the data model will be updated. If you changed the database connection string in web.config, and create a new database connection using different connection name, the Model Browser will start a new wizard to connect to the new database. In this way you can switch different database for the predefined Entity Framework.
