I got the same issue after upgrading the MySql NuGet packages from 6.9.8 to 6.10.6 in VS 2017 Community. I followed the accepted answer's instructions and downgrading back to 6.9.x fixed it. Upon futher investigation, Oracle has fixed the bug in the upcoming 6.10.7 release (https://bugs.mysql.com/bug.php?id=89134).

In short, until 6.10.7 is released, downgrade back to 6.9.x! I reverted back using the Nuget package manager and didn't have to change anything else to make it work.
