In Entity Framework, the model is prepared according to the requirement of the user. It depends upon the number of classes and categories that will be embedded into the database.
To perform various CRUD operations on the applications, model can also be configured manually, and it can be further modified to suit the required database.
Creating a model in Entity Framework Core has become easy for developers.
To design a model, it can either be done by coding it manually or by using the previous database model and tweaking it as per the requirement.
But with latest updates in the Entity Framework Core, there is a slight change in the approach for generating a model from an existing database.
Earlier the developers used the Database-First approach but now in the Entity Framework Core, the Code-First approach is used to generate Model using the existing database.
Code-First Approach to Generate Model using Existing Database
Command Line Interface
For creating a model using the existing database, the developer can use the Command Line Interface (CLI) tools, these tools help in generating SQL statements for model based on the existing database.
Using the CLI method, the developers can create as well as apply migrations and generate code for the model based on the existing model database. Another advantage of using the CLI approach is that the commands generated using this can be used for .NET core projects as well.
Before starting, don’t forget to create a folder.
Once the folder is created, navigate to this folder
Now, create another project
dotnet new console
After doing all this, add these Entity framework Core Tool and Packages, if you don’t have them.
