ASP.Net Core MVC (.Net 6.0) CRUD Operation

Introduction

We will learn CRUD (Create, Read, Update, and Delete) operations in ASP.NET Core MVC (.Net 6.0). We will use Entity Framework Core 6 to interact with the SQL Server database. We will use two Entity for CRUD operation.

Cover the following points in this blog.

• Create ASP.NET Core MVC 6.0 project in visual studio 2022
• Install all the necessary packages from NuGet.
• Create entities in the Model folder.
• Crete ApplicationDbContext class to interact with Database
• Add connection string of SQL Server database into appsettings.json file
• Run migration commands inside Package Manager Console (PMC)
  • Add-Migration "Initial"
  • Update-Database
• Add controllers inside the controller folder
• Add view models
• Add Views
• Add Validation

Prerequisites

• Visual Studio 2022 (.Net 6.0)
• SQL Server

Step 1. Create ASP.NET Core MVC 6 project

First, open Visual Studio 2022 and click on "Create a New Project" (highlighted in yellow color)

Search "MVC" in the Search box (Search for templates (Alt+s)) and select ASP.NET Core Web App (Model-View-Controller) as a project template and click the Next button.

Now, we install the above package one by one. Right-click on Dependencies and select "Manage NuGet Packages…"

Install Microsoft.EntityFrameworkCore package.

Install Microsoft.EntityFrameworkCore.SqlServer package.

Install Microsoft.EntityFrameworkCore.Tools package.

All install packages are showing in Dependencies -> Packages

Step 3. Add Category and Product entities class into the Model folder

Step 4. Add ApplicationDbContext class inside the Data folder

Step 5. Add connectionstring into appsettings.json

"ConnectionStrings": {
    "MVC6CrudConnetionString": "Data Source=DESKTOP-LOPK1F2;Integrated Security=true;Initial Catalog=MVC6CrudDb;TrustServerCertificate=True;MultipleActiveResultSets=true;"
}

Step 6. Add DbContext Service into Program.cs file with the connection string

Add-Migration "Initial" command

Update-Database command

MVC6CrudDb created into SQL Server with Categories and Products table.

Step 8. Add the Category controller and Product controller in the controller folder

In the same way, we added a Product controller, and now both are showing in the controller folder.
