Public virtual Department Department Īnd then create the DbContect – Database context class and name it Compan圜ontext.cs in the Models Folder. Let’s see the classes of entities are created. Once the command executes, we can see the Context Class and Entity Class created inside the Models folder. Step 4: Context Class and Entity Class Creation Just follow the command to execute as shown below:Ĭode: PM> dotnet ef dbcontext scaffold "Server= (your-server-name) Database=Company Trusted_Connection=True " -o Models Open Tools NuGet Package Manager- Package Manager Console.Ĭode: PM> dotnet ef dbcontext scaffold "Server=- Database=Company Trusted_Connection=True " -o Models Once creating all, the next step is to run the CLI Scaffold Command on the Package Manager Console Window. NET Core Command Line Interface-Scaffold Command is as follows, NET Core and ASP.NET Core in the dropdowns, then select Core ASP.NET Web App (Model-View-Controller) Create. Create a new ASP.NET Core Web Application dialog, choose. In the configuring new project dialog, enter a suitable name for your project and select Create. Then to create an application in Visual Studio, start the Visual Studio and choose “Create a new project.” In the “Create a new project” dialog, select ASP.NET Core Web Application – Next. WITH CHECK ADD CONSTRAINT FOREIGN KEY()ĪLTER TABLE. )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON ĪLTER TABLE. You can also create the tables using the following scripts in the Company Database.ĬONSTRAINT PRIMARY KEY CLUSTERED Let’s create the database and corresponding tables as shown below.Ĭreate the Company database in your SQL Server and create two tables, Employee and Department. The Database-First approach is only based on the database where the Entity Framework Core automatically creates the entity class and the context class from the database, which means we have to create the database for EF Core. Here we will explain with Database First Approach, which is the domain and the context class created based on the existing database. Net CoreĮntity Framework Core is the latest version the ORM Framework is a superior version of ADO.NET, which mechanizes the storage and retrieval of data from the database. Microsoft suggested using EF over ADO.NET or LINQ to SQL for the latest development. EF is Microsoft’s suggested data access technology for applications. Entity Framework executes the relevant question in the database and shows the results into instances of domain objects for work within the application. The Entity Framework communicates the queries against domain objects with the help of LINQ to entities. Furthermore, it performs CRUD operations, and it simply manages the relationship of “one to one,” “one to many,” and “many to many.” In addition, it can have inheritance relationships between entities. EF built the essential DB Commands for writing or reading data in the database and executes them for you. It takes the query results and automatically occurs in those results of application objects.Įntity Framework is an Open-Source Object Relational Mapper (ORM) that aims to increase the developer’s efficiency by decreasing the abandoned job of persevering data used in the application. EF is an Open-Source ORM Framework for ADO.NET the ORM takes part in building DB connections and executing commands. Entity Framework was released to interact between the relational database and. Net Core is an Object Relational Mapper (ORM), and the tool makes mapping with objects in software simpler than the tables of a relational database.
