Using LINQ to SQL in your phone app requires referencing the assembly System.Data.Linq
, which is included in the Windows Phone Framework Class Library (FCL).
There are two commonly used approaches to the creation of an application’s data model: code-first and database-first. Code-first entails writing your classes first, and then using those classes to generate the database. Conversely, database-first entails creating your database schema and then using a tool to generate an object model for interacting with the database. The database-first approach is discussed later in the chapter. For now, though, we concentrate on the code-first approach.
