    how to add the entity table in a modal folder using ado.net entity modal

    You have to right-click the Models folder in the Visual Stuido project and do an 'Add new Item'. The new item will be ADO.NET Entity Model that you will adding components needed into the Models folder like the Dbcontext and any entity class or classes into the Models folder.

     I am using VS2019 with MS SQL Server Express 2016, and I created the EF components using the wizard in the Models folder for an existing database with no trouble.  You're using MySQL, I am not familiar with it and I can't tell why it's not doing it for MySQL.

    Hi rahulpas,

    1. You need to open the MySQL Application Configuration tool, and then configure the entity framework.
      • The MySQL Application Configuration tool appears as a small icon on the Solution Explorer toolbar in Visual Studio. The icon is visible only when a project is active (with a connection to MySQL), and Connector/NET is installed 
    2. To install MySQL for Visual Studio you need to make sure that MySQL Server, MySQL for Visual Studio and Connector/NET are installed.
    3. Remarks: How to configure and use the EF6 features that are implemented in Connector/NET:https://dev.mysql.com/doc/connector-net/en/connector-net-entityframework60.html
      • You need toinstall MySql.Data.Entity through NuGet.

    Best regards,

    Hi rahulpas,

    You need to find your VS installation directory and open X:\XXXXXX\Microsoft Visual Studio\2019\Community\Common7\IDE\PrivateAssemblies, find the MySql.Data.dll file, then right-click the properties, and view "Details", You can see "Product version". If the version is 8.0.18, the installed mysql server version can only be up to 8.0.18,which can be lower.

    Note: You'd better first modify the version of mysql server, delete the configuration about mysql in web.config, and reinstall MySql.Data.Entity.

    Here is the result.

    Best Regards,
