OK so this is for all the devs in 2021 (Date: 2 Jan 2021)

This is Written thinking of all the New Devs out there if you Disagree on anything please comment, I merely have stated what worked with me with an intention to help

first, I will tell u my tech

Application Details:

• WPF Dekstop application on C#
• Framework is (.NetFramework 4.7.2)
• Database is MySQL

Installed in Windows 10 Machine :

• Visual Studio 2019 (16.8.2)
• MySQL [Server + workbench + Shell] (8.0.22)
• Connector / NET (8.0.22)
• MySQL for Visual Studio (1.2.9)

NuGet Packages Installed:

• Entity Framework (6.4.4)
• MySQL.Data (8.0.22)
• MySql.Data.EntityFramework (8.0.22)

Rules You Must Follow

1. You Must Have The above-Mentioned Packages and Softwares for It to work except MySQL Workbench

2. The Version of Connector/NET, MySQL.Data & MySql.Data.EntityFramework must be the same it doesn't matter what Version they are but all must be the same For Example, if its 6.10.9 then all three must be the same, but in the case of this example version MySql.Data.EntityFramework changes to MySql.Data.Entity as
   MySql.Data.EntityFramework was not intended for the older version and the latter was used before (please refer to the second last comment as of this day by @DavidRomo)

Things That Worked for me

- I already had the Packages mentioned above but for some reason, they just wouldn't work for me so if it's the same for you, Delete Connector And Mysql for visual Studio and reinstall them again and this time from the website and this is what worked for me

• This was in my App.config file, I do not know why the versions are written incorrect in this file, but this came preinstalled/prewritten like that, also I had tried manually changing the version to the exact correct version looking at some videos but for me it didn't work

  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>                
  
        ENTITY FRAMEWORK     
        <entityFramework>
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
      <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.EntityFramework, Version=8.0.22.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>
    </providers>
  </entityFramework>```
  
  
  

• It doesn't matter if its a x64 (a 64 bit software) or a x86 (a 32 bit software) MSI package when Installing From the MySQL website

• Don't care about the dependency packages that come pre-installed with it (like Bouncy castle)

• The point it started working 'FOR ME' was when I did not update the dependency packages, I let it install and did not mind

• I Tried Importing the Dll's that come with the connector but it didn't work for me at least ; EF6 still kept crashing after selecting the DB first approach, but I also didn't not import the other Dll's in File as well, like the Dll for Bouncy Castle and many others, so i do not know if that is a factor; So I removed the Imported Packages and Installed them from Nuget Package Manager with the dependencies

  this is the File Location If You Were Wondering but still this did not work ' FOR ME', meaning it might work for you if you tried the right way

  File Location : C:\Program Files (x86)\MySQL\MySQL Connector Net 8.0.22\Assemblies

• I personally Installed the "Connector/Net" and "MySQL for Visual Studio" MSI packages Manually from the Mysql Website, I did not Use the Installer, I have although Tried With it and it Kept Installing one version less from the latest Package

This has taken a lot of my time hope you guys don't have to deal with the same thing
