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

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”。

其他回答

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。

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。

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

以admin用户运行CMD。

from start menu 'cmd' - wait for it to find it. Right click on cmd, and select open as administrator type : cd C:\Program Files\Microsoft SQL Server\120\Tools\Binn type : SqlLocalDB start now type : SqlLocalDB info Shows the running sql instances available... choose what you want... to find more about the instance type : SqlLocalDB info instanceName now from VS you can setup your connection In VS, View/Server Explorer/(Right click) Data Connections/Add Connection Data Source: Microsoft SQL Server (SqlClient) Server name: (localdb)\MSSQLLocalDB Log on to the server: Use Windows Authentication Press "Test Connection", Then OK. job done

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。
