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

An implementation of this interface is used to initialize the underlying database when an instance of a DbContext derived class is used for the first time. This initialization can conditionally create the database and/or seed it with data. The strategy used is set using the static InitializationStrategy property of the Database class. The following implementations are provided: DropCreateDatabaseIfModelChanges<TContext>, DropCreateDatabaseAlways<TContext>, CreateDatabaseIfNotExists<TContext>.

public interface IDatabaseInitializer<in TContext> where TContext : DbContext
type IDatabaseInitializer<'Context (requires 'Context :> DbContext)> = interface
Public Interface IDatabaseInitializer(Of In TContext)

Type Parameters
