EF code first 生成edmx文件

通过下面的代码，你就可以拿到EF心中的地图 —— edmx文件。

using (var context = new Context())
{
    XmlWriterSettings settings = new XmlWriterSettings();
    settings.Indent = true;

    using (XmlWriter writer = XmlWriter.Create(@"Model.edmx", settings))
    {
        EdmxWriter.WriteEdmx(context, writer);
    }
}
