Scaffolding a Database Using Package Manager Console in Visual Studio

Open Visual Studio and create a new Console App (.NET Core) for C#.
Add the MySQL NuGet package for EF Core using the Package Manager Console. For example, use the following command to add theMySql.Data.EntityFrameworkCore v8.0.13 package:
```
Install-Package MySql.Data.EntityFrameworkCore -Version 8.0.13
```
Note

The version (for example, -v 8.0.13) must match the actual Connector/NET version you are using. For current version information, seeTable 9.2, “Supported versions of Entity Framework Core”.
Install the following NuGet packages by selecting either Package Manager Console or Manage NuGet Packages for Solution from the Tools and then NuGet Package Manager menu:
- Microsoft.EntityFrameworkCore.Design
  
  EF Core 1.1 only: Also add the MySql.Data.EntityFrameworkCore.Design package.
- Microsoft.EntityFrameworkCore.Tools version 1.1.6 (for EF Core 1.1) and Microsoft.EntityFrameworkCore.Tools version 2.0.3 (for EF Core 2.0)
  Note
  
  The .NET tools are included in the .NET Core 2.1 SDK and not required or supported for EF Core 2.1. If this is an upgrade, remove the reference to that package from the .csproj file (version 2.0.3 in this example) :
  <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.3" />
Open Package Manager Console and enter the following command at the prompt to create the entities and DbContext for the sakila database (adjust the connection-string values to match your settings for the user= and password= options):
```
Scaffold-DbContext "server=localhost;port=3306;user=root;password=mypass;database=sakila" MySql.Data.EntityFrameworkCore -OutputDir sakila -f
```
Visual Studio creates a new sakila folder inside the project, which contains all the tables mapped to entities and the sakilaContext.cs file.
