I have asp.net MVC application in which I am using database first approach , I have created Country , Cities and District table with following schema
Country(Id,Name)
City(Id,CountryID,Name)
District(Id,City_Id,Name)
Now I like to Add Country_ID as well into the district Table I am adding it in Database level and Updating my model from designer but after update when I tried to save I am getting lot of build errors
"Severity Code Description Project File Line Suppression State Error CS1061 'Activity' does not contain a definition for 'User' and no accessible extension method 'User' accepting a first argument of type 'Activity' could be found (are you missing a using directive or an assembly reference?) PPDMS D:\PPDMS-Backup_Lahore\PPDMS_after_File_Upload_To_folder\PPDMS\PPDMS\Controllers\ActivitiesController.cs 110 Active"
like this how to fix it without doing this change i got no build error
