Failed to find or load the registered .Net Framework Data Provider

Question

I got the following error: "Failed to find or load the registered .Net Framework Data Provider." It only occur in AppHarbor server, not my local

I use .Net mvc4 and mysql

I have added MySql.Data, MySql.Data.Entity, MySql.Web to reference and set Copy Local = true. I also push bin folder to AppHarbor

This is my web.config:

Any help is really really appreciated. Thank in advance

Have you tried using the NuGet packages?

• http://nuget.org/packages/MySql.Data
• http://nuget.org/packages/MySQL.Data.Entities

... they should make sure that right bits go where they are needed. You can use NuGet package restore to avoid pushing the package contents to AppHarbor.
