I like the other suggestions but I would rather not update the machine config for a single application  I suggest that you just add it to the web config   app config  Here is what I needed to use the MySql Connector NET that I  bin  deployed    lt system data gt       lt DbProviderFactories  gt           lt 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 6 4 0  Culture neutral  PublicKeyToken c5687fc88969c44d    gt       lt  DbProviderFactories gt   lt  system data gt
