    I currently have an SQL db that I'm trying to add a table column to, in order to allow for an extra field of user registration, using visual studio I accessed the dbml file, found the table required, and added the column there (made sure the datatype was correct and all the required CRUD backend is the C# handler ) the solution build successfully but once I access the registration page it throws an invalid column error.

    Any tips on how to handle this?
