Project –> Manage NuGet Packages… If you don’t have the Manage NuGet Packages… option you should install the latest version of NuGet.Upgrading is important because it gives you access to an improved API surface, that is much easier to use, as well as the latest bug fixes.įirst up, we need to get the latest version of Entity Framework from NuGet.

EXISTING UNIVERSAL DATABASE MODELS UPGRADE

If you are working in Visual Studio 2010 there are some additional steps you need to follow to upgrade to the latest version of Entity Framework. An App.config file has also been added to your project with the connection details for the database. Once the reverse engineer process completes the new model is added to your project and opened up for you to view in the Entity Framework Designer. Select the connection to the database you created in the first section, enter BloggingContext as the name of the connection string and click NextĬlick the checkbox next to ‘Tables’ to import all tables and click ‘Finish’ Select Generate from Database and click Next This launches the Entity Data Model Wizard Select Data from the left menu and then ADO.NET Entity Data ModelĮnter BloggingModel as the name and click OK We’re going to make use of Entity Framework Designer, which is included as part of Visual Studio, to create our model.

Select Windows from the left menu and Console Application.

To keep things simple we’re going to build a basic console application that uses the Database First to perform data access: The new database will now appear in Server Explorer, right-click on it and select New QueryĬopy the following SQL into the new query, then right-click on the query and select ExecuteĬONSTRAINT PRIMARY KEY CLUSTERED ( ASC)ĬONSTRAINT PRIMARY KEY CLUSTERED ( ASC),ĬONSTRAINT FOREIGN KEY () REFERENCES. Select OK and you will be asked if you want to create a new database, select Yes If you haven’t connected to a database from Server Explorer before you’ll need to select Microsoft SQL Server as the data sourceĬonnect to either LocalDB or SQL Express, depending on which one you have installed, and enter DatabaseFirst.Blogging as the database name Right click on Data Connections -> Add Connection… Let's go ahead and generate the database.

If you are using Visual Studio 2012 then you'll be creating a LocalDB database.

If you are using Visual Studio 2010 you'll be creating a SQL Express database.

The database server that is installed with Visual Studio is different depending on the version of Visual Studio you have installed: Typically when you are targeting an existing database it will already be created, but for this walkthrough we need to create a database to access. If you are using Visual Studio 2010, you will also need to have NuGet installed. You will need to have at least Visual Studio 2010 or Visual Studio 2012 installed to complete this walkthrough.

Video: WMV | MP4 | WMV (ZIP) Pre-Requisites The classes that you interact with in your application are automatically generated from the EDMX file.

The model is stored in an EDMX file (.edmx extension) and can be viewed and edited in the Entity Framework Designer. Database First allows you to reverse engineer a model from an existing database. This video provides an introduction to Database First development using Entity Framework. This video and step-by-step walkthrough provide an introduction to Database First development using Entity Framework.
