DataMigration in MVC and EF

I tinkered around with Data Migrations in MVC 4.0 and I have to say, It's really convenient.


Make sure connection string is updated to the desired database

• See ConnectionString 1: Standard

In NuGet package manager console

PM> Enable-Migrations -ContextTypeName Class1

• Class1 derives from DbContext
• -ContextTypeName is only needed if more than one class derives from DbContext

Note that some files are added to the Migrations folder

• configuration.cs
• Set  AutomaticMigrationsEnabled = true  to update database for development
• Seed(...) is used to update the database
• migration.cs
• The seed(...) method in Configuration is ran everytime update-database command is issued

To update the database

PM> update-database
