下载扩展并重新启动 Visual Studio 后,您应该能够将 ADO.NET 实体数据模型添加为新项目.当我努力学习旧版 Visual Studio 教程时,尝试使用视图">其他 Windows">数据源"等方法并没有做同样的事情.After installed Visual Studio 2013 and create a new MVC4 internet application project :Visual Studio Doesn't have Ado.net Entity Data Model when i click on add->new item->Why?I reinstall it but ther is no change ... 解决方案 Here's an updated solution I found as I had the same problem with Visual Studio 2015: ado.net model for db is gone Visual studio 2015Paraphrasing: Change your installation of Visual Studio 2015 and include the Microsoft SQL Server Data Tools (via Control Panel > Program & Features > VS2015 > Change > Modify > Windows and Web Development > Microsoft SQL Server Data Tools).After downloading the extension and restarting Visual Studio, you should be able to add ADO.NET Entity Data Model as a new item.As I learned the hard way trying to follow older Visual Studio tutorials, trying to use View > Other Windows > Data Sources etc. doesn't do the same thing. 这篇关于Visual Studio 中没有 ado.net 实体数据模型的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云!
