SSIS: Error --> Could not create a managed connection manager (VS 2010 - AdoNet MySql)

问题

I just upgraded my Connector/C# for Visual Studio and I get the error above. Everything seems fine, the preview queries work just fine in the package but upon execution this error occurs.

Before upgrading everything worked fine
I have deleted the pervious connection manager and added a totally new one
Test connection is succesfull

Anyone with the same problem in the past? There is a lot of speculation on 32/64 bit OSes, though MySQL official website states that even though the installer says x86, that means nothing (Note: MySQL Installer is 32 bit, but will install both 32 bit and 64 bit binaries.).

EDIT -> I tried connecting manually through an SSIS script to see if the coded exception provided more info. Unfortunatelly it provided even less

ConnectionManager connMan = Dts.Connections[7];
try
{
    connMan.AcquireConnection(Dts.Transaction);
}
catch (Exception ex)
{
    Dts.Events.FireError(-1, "Elt-Proc:", ex.Message, "", 0);
}

Found the answer:

Problem was with VS-2010, SSIS, and latest ADO .Net connector / MySQL For Visual studio.

I had installed the latest Connector/Net 6.7.4 and the MySQL for Visual Studio. I noticed that the version in the string at the connection properties was 6.6.5.

So I uninstalled the 6.7.4 version and re-installed the 6.6.5 version and worked like a charm.

I hope this will help others as well. It took way too much time for me to find out.

IMPORTANT: This error will also occur (on the server side) if SSIS Server and VISUAL STUDIO DEV Computer have different Connector/.Net Versions
