How to update the edmx if getting error of illegal mix collation(utf8_bin,none) and (utf8_bin,none) in mysql - collation

Question

I am getting error when updating the edmx
Unable to generate the model because of the following exception: 'An error occurred while executing the command definition. See the inner exception for details.
Illegal mix of collations (utf8_bin,NONE) and (utf8_bin,NONE) for operation '='
How do I solve this problem ? I have tried so many things. It would be great help if anyone help me to solve out this error.

When one is playing with the tools offered by Microsoft and Oracle simultaneously, the two don't always sit right with each other. Quite recently I had to integrate MySQL with Visual Studio using Entity Framwork and its was quite a mess.
As far as my research on the internet goes, most of the people trying to achieve the said target encountered the following problems or errors and I was unlucky enough to encounter all of them:
Authentication Probelm : "Authentication method 'caching_sha2_password' not supported by any of the available plugins"
Entity Framework doesn't generate the Entity Data Model:
Choose 'EF Designer from database'
Choose the connection from the drop down (localhost) that already tested successfully connecting to MySQL databse
The "Save connection settings in webc.config as" option is checked
I click 'Next' AND the window disappeared and I get back to the code window
No .edmx file is generated
Edmx file is generated but there is no Entity Data Model in it and the output windows shows one of the following 2 exceptions: "Illegal mix of collations (utf8_bin,NONE) and (utf8_bin,NONE) for operation '='" OR "Illegal mix of collations for operations 'Union'"
Entity Framework version is not compatible with the one required by MySQL.
MySQL Integration with Visual Studio Guidelines
Requirements:
Visual Studio 2012 or above
Dot Net Framework 4.5 or above
MySQL Installer Community 5.7.23.0
MySQL Workbench Community 6.3.9-winx64
MySQL Connector\Net 6.8.8
MySQL For Visual Studio 1.2.7
Entity Framework 5
Installation Steps:
Install the target version of Visual Studio first i.e. VS-2012 or above. The order of installation does matter.
Download the above mentioned MySQL’s components separately.
Install the MySQL Installer Community 5.7.23.0 and let it install all the default components. Select "Sha256_Password" authentication instead of "Caching_Sha2_password".
After its finished installing, close the MySQL installer and reopen it from the start menu.
Click on the “remove” option.
Uninstall MySQL for Visual Studio, MySQL Connector\Net and MySQL Workbench.
Run the setups for MySQL Connector\Net 6.8.8, MySQL for Visual Studio 1.2.7, & MySQL Workbench Community 6.3.9-winx64 individually and install them manually one by one.
Now the MySQL environment is all set to be integrated with Visual Studio and Entity Framework.
Note:
The versions of the MySQL Components plus the environment of Visual Studio and its frameworks should exactly match with the ones mentioned above otherwise the things will not be cohesive and the developer will end up dealing with some unwanted and rigid problems.
