警告

This documentation is for EF7 onwards. For EF6.x and earlier release see http://msdn.com/data/ef. 本文档是基于EF7版本.对于EF6.x及更早的版本请参见 http://msdn.com/data/ef.

注解

This article uses EF 7.0.0-rc1 which is the latest pre-release available on NuGet.org. You can find nightly builds of the EF7 code base hosted on https://www.myget.org/F/aspnetvnext/ but we do not maintain up-to-date documentation for nightly builds.

注解

The configuration in this section is applicable to relational databases in general. The extension methods shown here will become available when you install a relational database provider (due to the shared EntityFramework.Relational package).

Default Schema

The default schema is the database schema that objects will be created in if a schema is not explicitly configured for that object.

Conventions

By convention, the database provider will chose the most appropriate default schema. For example, Microsoft SQL Server will use the dbo schema and SQLite will not use a schema (since schemas are not supported in SQLite).

Data Annotations

You can not set the default schema using Data Annotations.

Fluent API

You can use the Fluent API to specify a default schema.
