Patterns are a great way of reusing knowledge between software applications. One well-known pattern is the Repository pattern, described by Martin Fowler (among others). This week, Liam McLennan shows how to implement the Repository pattern using the latest data access tools available in .NET 3.5, LINQ-to-SQL. One of the key benefits of this approach is that it allows the domain model to free itself of direct dependencies upon the infrastructure (the database).
