1. Right click on your Project and select add new Item. from Add New Item and select "ADO.net Entity Data model". Give the name and all necessary things, attach your DB and signing credentials. after finishing a .edmx file will add at your project.
2. open the edmx file and right click on the design view and select "add Code Generation item". Add new Item panel appears. from the panel select "ADO.net DbContext Generator". give the name and add it.
3. Crete a object of DbContext Class. use that DbContex Object methods to insert/Update/Delete command to do your job.
