This is just some boilerplate stuff that let’s us get some json, send some json, deserialize it appropriately in our client. Add the following constructor, which will allow configuration to be passed into the context by dependency injection.So, we need to move database provider configuration there. In ASP.NET Core, things like dependency injection, services that are going to be used, generally configured in Startup.cs class. We’ll also rename our context to OrderContext.cs and Orders.cs to Order.cs since it’s more logical that way. Now we need to add a Data folder and put our context there to conform with the separation of concerns pattern. The context represents a session with the database and allows you to query and save instances of the entity classes. The entity classes are simple C# objects that represent the data you will be querying and saving.
The reverse engineering process created entity class Orders.cs, and a derived context orders_databaseContext.cs based on the schema of the existing database. Scaffold -DbContext "Server=localhost\SQLEXPRESS Database=orders_database Trusted_Connection=True " Microsoft. Tools –> NuGet Package Manager –> Package Manager Console.To do that you need to replace server connection string with your own and run this command from NuGet console in Visual Studio: Now it’s time to create the EF model based on existing database. File –> New project –> ASP.NET Core Web Application.We’ll kick things off by creating a new Web API project. Open SQL Management Studio, then right click Databases -> Restore database. The database can be found here on Github. In order to follow along this blog post you’ll need to import Orders database into your SQL Server. Microsoft SQL Server Express with management tools.

Visual Studio 2017 – Community is free for students, hobbyists and startups.What should I have installed in order to follow along? So, today our task will be to scaffold an API from my existing SQL Server database and create a simple UI to present the data to the users. A couple of days ago, during the regular cleaning of my hard drive, I’ve found an old database with Orders data from my previous projects.

If you write software for a living or just for fun, you’ve probably worked with databases before. Today, I thought I would continue this little Microsoft streak and dive into another Microsoft products – ASP.NET Core 2.0 and EF Core. Oh hey there! In my last blog post I looked at Microsoft Cognitive Services.
