I create a connection with MySQL using asp.net edmx file but show error on update. In my project a ssdl file is also included. i don't know how to upd开发者_StackOverflow社区ate ssdl file but update the edmx file and it is updated successfully and also verified mapping. My new table is mapped successful but it shows the following error on runtime:

Error 3027: No mapping specified for the following EntitySet/AssociationSet - DiscoveredDevices, Images, Logs, Subnets, Users, Roles, ImageDeployments, OSTypes, ImageDeplymentProgressInfoes, ProcessorLoadPercentages, MemoryStatus, HDDStatus1, ActiveClients, PasswordRecoveryEmailSettings, Settings, DeploymentLoginCredentials.

Any idea how to resolve this error?

You have entities in your model that are no longer in your DB tables or vice versa. You need to manually update your model to fix this. This often occurs if you update your Database tables (renaming or deleting columns/tables) and then just click update model from Database

You will find more information in the Mapping Details of each entity.
