Dbml file not updating
DBML display does not show new foreign key constraints In the case of stored procedure update, you should delete it from the file and reinsert it again.But if the stored procedure have two paths (ex: if something; display some columns; else display some other columns), make sure the two paths have the same columns aliases!!! The LINQ to SQL tools is the feature you must install.For VS 2017/2019, you can find it under Check out the PLINQO site at have a look at the intro videos.Of course, I can't share my company's code so you're on your own for writing this yourself.
So Microsoft decided to stop investing in Linq to SQL and put al its effort in Entity Framework.
For instance, I may create a new table, new fields within tables and change the null/isnull values for the columns.
