String connectionString = "Server=localhost\\SQLEXPRESS Database=testdb Trusted_Connection=True " Step 5: Now, add the following code in Program.cs file to register the OrderService and call its DisplayOrders() methods from Main method using EFCoreDBContextApplication.Models Join customer in _dbContext.Customers on order.CustomerId equals customer.CustomerIdĬonsole.WriteLine($"Order Details are: Customer Name: ") Join product in _dbContext.Products on order.ProductId equals product.ProductId Var OrdersList = (from order in _dbContext.Orders Public OrderService(testdbContext context) ![]() Step 4: Now, create new C# class file OrderService.cs and write the below code to DisplayOrders on the Console Output window: using EFCoreDBContextApplication.Models OR Generate DBContext and Models Using Powershell / Nuget Package Manager Console by running following command: Scaffold-DbContext "Server=localhost\SQLEXPRESS Database=testdb Trusted_Connection=True " -OutputDir ModelsĪbove dbcontext scaffold command will create the Models folder with all the tables inside the testdb database will be created as Model files in Models folderĪfter database Scaffold, the project structure files looks like following: NET CLI command: dotnet ef dbcontext scaffold "Server=localhost\SQLEXPRESS Database=testdb Trusted_Connection=True " -o Models NET CLI tools: In the below command we are installing dotnet ef tool globally. Step 3: Now, the next step is to Scaffold the DbContext and Models from already created database, to begin with, install the required. NET CLI commands: dotnet add package Microsoft.EntityFrameworkCore dotnet add package dotnet add package dotnet add package Now add the required NuGet packages through following. NET Core console application in the "EFCoreDBContextApplication" output directoryįirst change the directory to Project directory: cd EFCoreDBContextApplication NET CLI command or using Visual Studio Editor: dotnet new console -o EFCoreDBContextApplication NET Core console application using below. NET Core to use the DBContext object to perform DB operations: NET Core we can perform the CRUD operation using Entity Framework Core, following steps help to add Entity Framework Core DBContext file and list of Models using Scaffold DbContext and use the. NET Core project, and using Dependency Injection in. ![]() Entity Framework Core helps to add the DBContext file and all the models into the.
