The first connection string is named DefaultConnection and is used for the membership database to control who can access the application. The two connection strings are very similar. The following example shows a portion of the Web.config file with the new connection string added: (Not the Web.config file in the Views folder.)Īdd the following connection string to the element in the Web.config file. Open the application root Web.config file shown below. For more information see SQL Server Connection Strings for ASP.NET Web Applications. In Visual Studio 2017, LocalDB is installed by default with Visual Studio.īy default, the Entity Framework looks for a connection string named the same as the object context class ( MovieDBContext for this project). However, a LocalDB database can be easily migrated to SQL Server or SQL Azure. LocalDB in particular should not be used for production with a web application because it is not designed to work with IIS. SQL Server Express is not recommended for use in production web applications. Typically, LocalDB database files are kept in the App_Data folder of a web project. LocalDB runs in a special execution mode of SQL Server Express that enables you to work with databases as. LocalDB is a lightweight version of the SQL Server Express Database Engine that starts on demand and runs in user mode. In this section we'll explicitly add a connection string in the Web.config file of the application.
You don't actually have to specify which database to use, Entity Framework will default to using LocalDB.
One question you might ask, though, is how to specify which database it will connect to.
The MovieDBContext class you created handles the task of connecting to the database and mapping Movie objects to database records. Is the preferred approach for new app development.Ĭreating a Connection String and Working with SQL Server LocalDB.We recommend you try the Razor Pages tutorial before the MVC version. Razor Pages is a new alternative in ASP.NET Core, a page-based programming model that makes building web UI easier and more productive. This tutorial teaches ASP.NET Core MVC with controllers and views. The new tutorial uses ASP.NET Core MVC, which provides many improvements over this tutorial. 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.An updated version of this tutorial is available here using the latest version of Visual Studio.
I tried every way to connect Visual Studio's Server Explorer to LocalDB. 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. The program runs and entries are added to the database and outputted in the console. I don't have any other instances of SQL installed on my local computer. I also verified that I have Microsoft SQL Server 2012 Express LocalDB installed which came with Visual Studio 2013. I created the project and installed the latest EF Nuget package for the project to compile.
I'm following this article on Entity Framework 6.0 which gives a simple walk-through on Code First. I can't believe I couldn't find a working solution to this after an hour of searching.
