Hi, support long thinking on solution this problem, so may you guys can help me. I want to add additional external database (it will be MySQL from Azure).

I done it on my local computer (it's working great!) but when I putted it to dev stage it doesn't work.

I catch exception:

"System.Data.Entity.Core.ProviderIncompatibleException: An error occurred accessing the database. 
This usually means that the connection to the database failed. 
Check that the connection string is correct and that the appropriate DbContext constructor is being used to specify it or find it in the application's config file.

 See http://go.microsoft.com/fwlink/?LinkId=386386 for information on DbContext and connections. 
 See the inner exception for details of the failure. ---> System.Data.Entity.Core.ProviderIncompatibleException: The provider did not return a ProviderManifestToken string. ---> MySql.Data.MySqlClient.MySqlException: Unable to connect to any of the specified MySQL hosts.\r\n   at MySql.Data.MySqlClient.NativeDriver.Open()\r\n   at MySql.Data.MySqlClient.Driver.Open()\r\n   at MySql.Data.MySqlClient.Driver.Create(MySqlConnectionStringBuilder settings)\r\n   at MySql.Data.MySqlClient.MySqlPool.GetPooledConnection()\r\n   at MySql.Data.MySqlClient.MySqlPool.TryToGetDriver()\r\n   at MySql.Data.MySqlClient.MySqlPool.GetConnection()\r\n   at MySql.Data.MySqlClient.MySqlConnection.Open()\r\n   at MySql.Data.MySqlClient.MySqlProviderServices.GetDbProviderManifestToken(DbConnection connection)\r\n   at System.Data.Entity.Core.Common.DbProviderServices.GetProviderManifestToken(DbConnection connection)\r\n

Do you have any idea, solution for that?
