Entity Framework – C# – CodeFirst – Video

After the first two videos for C# Entity Framework (Video 1 and Video 2) I have decided to make a small one for the Code First approach.

entity-framework

I have used the materials of SoftUni here, mainly concentrating on problem 3. Then I simply played a bit with the migrations in C# to see what they can do. In general – they do their job. 🙂

The code for from the video is mainly here. The MSDN is here. To summarize the MSDN, these are probably the most important commands:

  • Enable-Migrations *run in Package Manager Console to start the migration party
  • Add-Migration *scaffolds the next migration based on changes you have made to your model since the last migration was created
  • Update-Database * applies any pending migrations to the database
  • Update-Database –TargetMigration: AddBlogUrl
  • Update-Database –TargetMigration: $InitialDatabase *rolls back to empty DB
  • Update-Database -Script -SourceMigration: $InitialDatabase -TargetMigration: AddPostAbstract *gets SQL Script
The video is in YouTube:

I hope you have enjoyed it! 🙂
