LINQ to SQL is NOT dead!

Ever since Microsoft announced that the Entity Framework was their ORM of choice, people everywhere have been saying, “LINQ to SQL is dead!” A lot of people feel like they’re not allowed to use LINQ to SQL anymore and that they have to use Entity Framework instead.

In fact, LINQ to SQL is not only alive and well, Microsoft has even announced LINQ to SQL improvements in .NET 4.0, including finally adding using ITable<T> for tables instead of Table<T>, which makes it much easier to test. Combine that with this open source tool that will create an IDataContext interface for you and you’re on your way to testable LINQ to SQL. So no, LINQ to SQL is not dead!!

Look, just because Microsoft says you should do something a certain way doesn’t mean that you have to do everything that they say. For example, Microsoft will almost never recommend using an open source software package over something that they’ve built (I say almost never because I’m sure they’ve done it at some point, but I’ve never seen it done). That certainly doesn’t mean that the Microsoft product is better than every open source tool.

For example, if you’re going to use an ORM, LINQ to SQL can get the job done for you, but if you’re looking for an ORM with more features, you owe it to yourself to check out Fluent NHibernate.
