ClearDatabaseSchemaIfModelChanges<'TContext> Class

 

An implementation of IDatabaseInitializer<'TContext> that will DELETE all resources (e.g. tables, views, functions, and procedures) within a given database schema, and optionally re-seed the database only if the model has changed since the database was created. This implementation of IDatabaseInitializer<'TContext> is useful if the current user only has permission to access resources within a particular database schema and not the entire database.
