I can't believe I couldn't find a working solution to this after an hour of searching. I'm following this article on Entity Framework 6.0 which gives a simple walk-through on Code First. I created the project and installed the latest EF Nuget package for the project to compile. I also verified that I have Microsoft SQL Server 2012 Express LocalDB installed which came with Visual Studio 2013. I don't have any other instances of SQL installed on my local computer. The program runs and entries are added to the database and outputted in the console. But when the article says "check your localdb" it doesn't say how! I don't see any '.mdf' or '.ldf' files created under the project folder. I tried every way to connect Visual Studio's Server Explorer to LocalDB. The wizard cannot locate (localdb) or cannot find any provider in Server Explorer to accept connection string like (localdb)\v11.0;Integrated Security=true; I've seen this asked several places in StackOverflow but no answer works or marked as answer. Please help, this doesn't have to be this frustrating!

连接Visual Studio服务器资源管理器到LocalDB的步骤是什么?


当前回答

在Visual Studio 2017中最快的方法是转到Tools -> SQL Server -> New query..从Local databases中选择,并在底部选择所需的数据库名称。

替代方法

Visual Studio 2017服务器名称为:

(localdb)\MSSQLLocalDB

使用菜单工具添加新的连接->连接到数据库…

其他回答

我遵循了上面的步骤,但我忘记在Visual Studio 2015配置之前安装SQL Server 2014 LocalDB。

我的步骤如下:

安装SQL Server 2014 LocalDB; 打开Visual Studio 2015和SQL Server对象资源管理器; 在SQL Server标记下找到您的LocalDB。

希望这对大家有所帮助。

Visual Studio 2015 RC,已经安装了LocalDb 12,类似于之前的说明,但仍然不应该被要求知道“魔术”,在使用之前,默认实例应该已经打开… 咆哮完毕,无解:

cmd> sqllocaldb start

会显示

LocalDB instance "MSSQLLocalDB" started.

您的实例名可能不同。无论哪种方式,弹出到VS,打开服务器资源管理器,右键单击数据连接,选择添加,选择SQL Server,在服务器名类型中:

(localdb)\MSSQLLocalDB

不输入数据库名称,单击“Test Connection”。

只需将ParentInstance更改为MSSQL14E。LOCALDB或mssql15 .LOCALDB。

修理不起作用。

与示例插图中一样,所有这些步骤都只提供对“系统”数据库的访问,而没有选择要访问的现有用户数据库的选项。

访问本地(非Express Edition) Microsoft SQL server实例的解决方案驻留在SQL server端:

打开运行对话框(WinKey + R) 类型:“services.msc” 选择SQL Server浏览器 单击“属性” 将“禁用”改为“手动”或“自动” 当“Start”服务按钮启用时,单击它。

完成了!现在,您可以从连接属性中的“服务器名称”列表中选择本地SQL Server。

使用SQL Server 2017和Visual Studio 2015,我使用本地主机\SQLEXPRESS
