Answer 1

I've had the same problem, I have found a solution to it .. problem exists in ConnectionString , change it from :

connectionString="Data Source(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-WebApplication3-20160303101342.mdf;Initial Catalog=aspnet-WebApplication3-20160303101342;Integrated Security=True"

To :

  connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=YourDatabaseName;Data Source=YourServerName"

And it will work without any other changes

Answer 2

Did you created database using migrations?

If not, open package manager console in VS(Tools -> NuGet Package Manager -> Package Manager Console)

In command line you have to enable migrations with command.

Enable-Migrations -EnableAutomaticMigrations

after that run command

Update-Database

and start project.

Answer 3

Please follow these tutorial . You need to enable migration, add first migration with your models and update database.

Answer 4

It looks like the tutorial either skipped the database creation part or is behind the latest VS 2013 templates. The Databases is missing when you create a new MVC project. In addition, the tutorial register a user via username while the project wants you to use email addresses.

Answer 5

Go to package Manager Console

step 1 Run Below command

enable-migrations

Step 2 Run below command

add-migrations InitialModel

Step 3 and last run the command

update database
