Answer 2

I had same mistake. The reason was in the difference between mysql-connector-net version and MySQL.Data.Entity version. I uninstalled mysql-connector-net, then installed correct version, and the wizard started to work normally.

Answer 3

Hello I tried this today. I like to share my solution working for VS 2017. First install MySQL for Visual Studio. Then install the MySQL Connector 6.10.7. Now you are able to do everything else: Inside your project install some NuGets MySQL.Data and the MySQL.Entity: Both with version 6.10.7. The VS 2017 does not close anymore and the model window is opened.

Answer 4

I Hint also first install MySQL for Visual Studio. Then install the connector. This solves two issues: You can use MySQL in Visual Studio and you connect stable to a database.

Please, ensure what 3per mentions: MySQL.Data and MySQL.Data.Entity has to the same version.

Hope this helped others a lot.
