Adding the relevant dependencies to the project.json file

If you want to use ASP.NET Identity with Entity Framework in your application, you need to add the following dependencies:

"EntityFramework.Commands": "7.0.0-rc1-final", 
    "EntityFramework.MicrosoftSqlServer": "7.0.0-rc1-final", 
    "Microsoft.AspNet.Authentication.Cookies": "1.0.0-rc1-final", 

Create an appsettings.json file and store the database connection string.

Create a file with the name appsettings.json at the root level of the project, as shown in the following screenshot:

Store the following connection string in appsettings.json. This connection string will be used by ASP.NET Identity to store the data in relevant tables:

{ 
  "Data": { 
    "DefaultConnection": { 
      "ConnectionString": "Server=(localdb)\\mssqllocaldb;Database=aspnet_security;Trusted_Connection=True;MultipleActiveResultSets=true" 
   } 
  } 
}
