Fix MVC EF Code first error: Model compatibility cannot be checked because the Edmmetadata type is not included in the model.

checked  in the model. Ensure that includemetadataconvention have been added to the Dbmodelbuilder conventions.

Analysis:

This error was encountered because EF Code first was used to build the database, and the model was modified after the database was built.

Two ways of solving this:

1. In the Application_Start () method of Global.asax.cs, database.setinitializer<xxxdbcontext> (New Databaseinitializer ()) Change to Database.setinitializer<xxxdbcontext> (NULL) (if there is a data method for initializing the database)

2. Delete the database (with no symptoms).

 Use MASTER GO DROP DATABASE [DBNAME]
