Question

I am working on MVC and in the model I created a class that uses Entity
Framework. I am trying to inherit from DBContext class but it is showing
an error saying: “The type or Namespace name DBContext doesn’t exist”. I also
added the “System.data.Entity ” namespace.

Example like :

 public Class SampleEF :DBContext //Showing error
{

}

Can you please tell me how to use the DBContext class to work with EF?

Answer 1

Firstly Add Reference to System.Data.Entity in your project by Right Click your project in Solution explorer and Select Add Reference. Then use the using statement as below:

using System.Data.Entity;
using System.Data.Entity.Infrastructure;

Then write your Context Class as:

public Class SampleEF : DbContext 
{

}
