Connection string is added in a different location than the templates

[Tratcher]

If you use scaffolding to create a dbcontext while creating a controller it will add a connection string to appsettings.json and the code to read it in ConfigureServices. However, it's still using the location and APIs that were used in the RC1 templates and does not match the RC2 or RTM templates.

scaffolding:

            services.AddDbContext<WebApplication6FooContext>(options =>
                    options.UseSqlServer(Configuration["Data:WebApplication6FooContext:ConnectionString"]));

  "Data": {
    "WebApplication6FooContext": {
      "ConnectionString": "Server=(localdb)\\mssqllocaldb;Database=WebApplication6FooContext-d43134d2-a078-4fac-a02c-a871317c4236;Trusted_Connection=True;MultipleActiveResultSets=true"
    }
  }

template:

            services.AddDbContext<ApplicationDbContext>(options =>
                options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

  "ConnectionStrings": {
    "DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=aspnet-WebApplication4-63f9d57e-b6e6-4a3a-950d-c82b28384751;Trusted_Connection=True;MultipleActiveResultSets=true"
  },
