Hi Rahul, The fundamental difference is in Code First you design the DB in your code . This gives you full control over the code and design . In DB first approach you already have a DB designed to you by the designers. Now you have to develop you code based on that design . Detailed Difference : Code first Very popular because hardcore programmers don't like any kind of designers and defining mapping in EDMX xml is too complex. Full control over the code (no autogenerated code which is hard to modify). General expectation is that you do not bother with DB. DB is just a storage with no logic. EF will handle creation and you don't want to know how it do the job. Manual changes to database will be most probably lost because your code defines the database. Database first Very popular if you have DB designed by DBAs, developed separately or if you have existing DB. You will let EF create entities for you and after modification of mapping you will generate POCO entities. If you want additional features in POCO entities you must either T4 modify template or use partial classes. Manual changes to the database are possible because the database defines your domain model. You can always update model from database (this feature works quite good). I often use this together VS Database projects (only Premium and Ultimate version).

Rahul, In Model first we design the DB model and then generate a database and classes based on the model.
