Re: v6.7.4 installed, but 6.6.5.0 attempted to load. - Solved

[Hugh Leighton]

Solved my problem. I was missing a step of adding db Provider factory into the App.Config. I added:
<system.data>
<DbProviderFactories>
<add name="MySQL Data Provider"
invariant="MySql.Data.MySqlClient"
description=".Net Framework Data Provider for MySQL"
type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.7.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>
</system.data>

and it worked as expected. The hardest part was sorting out that the PublicKeyToken is the same for different connector versions.

Thanks
