![]() ![]() You will have to create a service that return entities, basically a wrapped entity framework database provider. In one Context you have your DBSets for users and in the other the rest. Both pointing to the same database but with different ApplicationDbContext. ![]() This table contains information about student information. From my understanding you need two DbContexts in you Startup class. WILMODBContext is the context for the following model. In this example, I use the following two tables of two different databases. For creating the Entity Framework model click here. And I will contimue to post a few more articles related to MVC, Entity and many more.Ī sample application is attached as a reference. Step 1 First of all, create two contexts that refer to two different databases. Hope it will be helpful somewhere someday. It's very simple in use, we just need to understand how to implement this. Now I run the sample application and press F5. You can see the code snippet in the above diagram states that we are using an inner join on two tables, Orders and OrderDetails, and return the result to the view (that is of type OrderModel having the following code snippet). Now open the RegisterController class file and write my code in Action "Verify" also as shown in the following image: Now let's proceed further and get to the core topic to use Joins with Entity Framework. These are the very basic steps to create an entity object from an existing database as shown above. Select the required database objects as per your needs and click on the "Finish" button.Īn edmx file will be added into the solution as per the image show under the following: Select "Generate from database" and click "Next" the following window will appear:Ĭlick on "New Connection" and fill in the required details as shown in the following image to connect with the server (in this for example I have used "local DB Server").Ĭlick on "Test Connection" to verify that the connection has been established.Ĭlick "Next", the following window will appear: Right-click on the Model folder and proceed as shown in the following screenshot:Ĭhoose "Visual C#" => "ADO.NET Entity Data Model" then provide the name as you need to (for exampleNorthwind.edmx) as in the following:Ĭlick "Add" then a new window will appear as in the following: Create a sample MVC application and follow the procedure below.ġ. Kindly follow the following procedure to create a DBContext. We need to create DB Context object to understand the fact and advantages, so let's create a. I will use a sample application to demonstrate this feature. In this article I am sharing how to use joins in Entity Framework with a DB context and a LINQ query. NET Framework collections, SQL Server databases, ADO.NET Datasets, and XML documents. Visual Studio includes LINQ provider assemblies that enable the use of LINQ with. ![]() LINQ introduces standard, easily-learned patterns for querying and updating data, and the technology can be extended to support potentially any kind of data store. Language-Integrated Query (LINQ) is a set of features introduced in Visual Studio 2008 that extends powerful query capabilities to the language syntax of C# and Visual Basic. ![]()
