When I install the latest MySQL dotConnect, I start getting errors.

The base class or interface 'Devart.Common.DbTransactionBase' in assembly 'Devart.Data, Version=5.0.302.0, Culture=neutral, PublicKeyToken=09af7300eec23701' referenced by type 'Devart.Data.MySql.MySqlTransaction' could not be resolved

The only way I resolved this in the past was to ensure both Oracle and MySQL dotConnect are at the same level.

What is a better way to resolve this?

Devart data providers use a common assembly (Devart.Data.dll), so it is necessary to install compatible providers versions (they have the same release date):

You can find the versions of your current products via the Tools > Oracle (MySQL) > About menu of Visual Studio.

dotConnect for MySQL v 6.30.202 is compatible with dotConnect for Oracle v 6.30.202.
