AddTable

Using the AddTable method allows you to create a new table for an entity class. On adding a new table, the DatabaseSchemaUpdater also applies the metadata associated with the entity class and creates any related indexes or foreign key constraints.

To add a new entity to the Twitter data model, we first create that entity and decorate it with Table and Column attributes. In the following example, the TwitterFriend class represents a Twitter user, who happens to be a contact of another Twitter user (see Listing 29.10). TwitterFriend contains an Id and a ScreenName property. In addition, an index is declared for the ScreenName property.
