Why am I getting a runtime error?

Question

Sir,   I have developed ASP.NET MVC4 project using entity framework. But why am I getting a runtime error? What is the solution for this?   Kindly reply me.     The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.

I think Enttiy Framework is not correctly installed in your project . Do One Thing Create a new solution inside that just paste the files of your previous project to new one . Right click on Project and manage nuggets and Install EF 6 i hope this will resolve the issue.
