How to connect to MySQL server using Entity Framework Core

I am using Visual Studio 2019 community edition. I want to connect to MySQL using Entity Framework core. I do not want to use Entity Framework 6.

I am running into following issues:

  1. I created a new project using "ASP .NET CORE App and ASP .NET CORE Web App" template and it does not show option to add Entity Framework.

  1. If I use tools > Connect to Database option from menu, I do not see option to connect to MySQL. How can I enable this option.

    Install "Pomelo.EntityFrameworkCore.MySql" using the NuGet Package Manager in Visual Studio 2019.

    Then follow the instructions to configure it in your project:

    Disclaimer: I have made a small number of contributions to the Pomelo package.

    EFCore is a package, not a file you would add to your project. Go to Project>NuGet Package Manager and install Microsoft.EntityFrameworkCore, Microsoft.EntityFrameworkCore.Tools. Then you can scaffold the connection to your database by running the scaffold-dbcontext command in the PM console.

    did you try installing through the console?

    Install-Package Microsoft.EntityFrameworkCore -Version 5.0.11

    make sure that this source is added to your nuget sources in VS

    Step by Step - Database First

    First install these packages

    1. Microsoft.EntityFrameworkCore.Design

    So on Powershell go to project folder [right click on project and select open in terminal (visual studio)]

    enter image description here

    Now, you can run this command

    enter image description here

    dotnet ef dbcontext scaffold "Servel=localhost;Database=tempSQLonNetCore;user=root;password=;" "Pomelo.EntityFrameworkCore.MySql"

    If your connection is true, your DbContext Generated and entities adding to your project.

    Now you must inject DbContext, Described in the Codefirst section

    Step by Step - Code First

    First install these packages

    1. Microsoft.EntityFrameworkCore
    2. Microsoft.EntityFrameworkCore.Tools
    3. Pomelo.EntityFrameworkCore.MySql

    Add connection string look like in appsetting.json

    "ConnectionStrings" : {
        "DefaultConnection" : "Servel=localhost;Database=tempSQLonNetCore;user=root;password=;"

    **Now, Create your DB context **

    public class ApplicationDbContext : DbContext
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
        // Your Entities

    finally configure the app for connecting

    var connectionString = builder.Configuration.GetConnectionString("DefaultConnection");
    builder.Services.AddDbContext<ApplicationDbContext>(options => {
         options.UseMySql(connectionString, ServerVersion.AutoDetect(connectionString));

    Now you can use Migration if you need to create or update your database Migration
