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

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。

请使用SQL Server对象资源管理器(SSOX)

与其他答案不同,这种方法使用: —无特殊命令。 —无复杂配置。 只需使用SQL Server对象资源管理器

这很简单……

从“视图”菜单中,打开SQL Server对象资源管理器。

右击{YourTableName}表>视图设计器

完成了。

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。

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…

场景:Windows 8.1, VS2013 Ultimate, SQL Express已安装并运行,SQL Server浏览器已禁用。 这招对我很管用:

First I enabled SQL Server Browser under services. In Visual Studio: Open the Package Manager Console then type: Enable-Migrations; Then Type Enable-Migrations -ContextTypeName YourContextDbName that created the Migrations folder in VS. Inside the Migrations folder you will find the "Configuration.cs" file, turn on automatic migrations by: AutomaticMigrationsEnabled = true; Run your application again, the environment creates a DefaultConnection and you will see the new tables from your context. This new connection points to the localdb. The created connection string shows: Data Source=(LocalDb)\v11.0 ... (more parameters and path to the created mdf file)

您现在可以创建一个新的连接 服务器名称:(LocalDb)\v11.0(点击刷新) 连接到数据库:在下拉菜单中选择新数据库。

我希望这能有所帮助。

这对我很管用。

打开命令提示符 运行"SqlLocalDB.exe start" 输出说明"LocalDB instance "mssqllocaldb" started." 在VS中,查看/服务器资源管理器/(右键单击)数据连接/添加连接 数据来源:Microsoft SQL Server (SqlClient) 服务器名称:(localdb)\MSSQLLocalDB 登录服务器:使用Windows身份验证 按“测试连接”,然后确定。
