Definition

Namespace:
System.Data.Entity System.Data.Entity System.Data.Entity
Assembly:
EntityFramework.dll

An implementation of IDatabaseInitializer that will DELETE, recreate, and optionally re-seed the database only if the model has changed since the database was created.

public class DropCreateDatabaseIfModelChanges<TContext> : System.Data.Entity.IDatabaseInitializer<TContext> where TContext : DbContext
type DropCreateDatabaseIfModelChanges<'Context (requires 'Context :> DbContext)> = class
    interface IDatabaseInitializer<'Context (requires 'Context :> DbContext)>
Public Class DropCreateDatabaseIfModelChanges(Of TContext)
Implements IDatabaseInitializer(Of TContext)

Remarks

Whether or not the model has changed is determined by the CompatibleWithModel(Boolean) method. To seed the database create a derived class and override the Seed method.
