My question is similar to this one but the crash happens later. I must interoperate an EF database-first model between SQL Server and MySQL. More specifical
For anyone who's still encountering this issue here are the versions that I had to install to get it working:
MySQL for Visual Studio: 2.0.5 (note that at the time of posting the latest General Availability release is 1.2.9 - you'll need to go to the Development Releases tab to get version 2.0.5 - https://dev.mysql.com/downloads/windows/visualstudio/)
MySQL Connector/NET: 6.9.11 (https://downloads.mysql.com/archives/c-net/)
MySQL.Data NuGet package: 6.9.11 (Install-Package MySql.Data -Version 6.9.11)
MySQL.Data.Entity NuGet package: 6.9.11 (Install-Package MySql.Data.Entity -Version 6.9.11)
(Note that I didn't have to adjust the config file.)
Hope it helps.
