After the last Update to  (from the Visual Studio Integration is broken. In VS2019 an Error occurs with Assembly Mysql.Data not found ( - repair doesn't work, reinstallation doesn't work.

How to repeat:
use installer and upgrade to

Suggested fix:
Don't know where to start and how to explain whats running wrong with the mysql team but it's horrible since it's under Oracles Hat.

Visual Studio Integration lags since Version VS2015. 
Take a look at the work log ... 

Please - fix it - we (the developers) creating software which uses MySQL Database and that's what you sell to our customers! I know that Oracle is a rich company but with unsatisfied external developers you'll see it (MySQL) die every day a little more and the End is - you (internal developers) are needless... ;-)

It's a misstyping in the version of the assembly not found.

It's  which couldn't found by the Visual Studio Integration part.

Assembly Mysql.Data not found ( - repair doesn't work, reinstallation doesn't work.

1.) Remove Visual Studio Integration
2.) Add Visual Studio Integration
3.) Start VS2019 
  a.) A couple of Machines Updating the MySQL Connection here
  b.) A couple of Machines are missing the VS Integration here then:
     Launch MySQL Installer again and go to modify mySQL Visual Studio part.
     Check if the corresponding checkboxes marked for installation 
  c.) on two machines I had to remove and reinstall  the .NET Connector 
      itself to make it accessible for VS2019
Start VS2019 again and wait a couple of seconds. Readd your DB Connections
