I develop an ASP MVC 5 App with entity framwork and MySQL. In local I run success. But when I move to hosting and run it throw exception.
System.Data.Entity.Core.ProviderIncompatibleException: An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string.
