It depends on whether the EF was created as database-first or code-first.
Given what you said, and assuming it was code-first, open the .edmx, right click and hit "Update Model from Database".  You can check off any new tables you want to add, but by default any existing tables will be updated with new / removed columns.

That is database-first. Just make a backup of your models in case the previous developer added code into the autogenerated classes

Go to the Powershell console.
Open VS and navigate to Tools/Package Manager Console
Then run Enable-Migrations (if you got an error, your developer already did this)

if the enable-migrations cmdlet works or fail you should create a new migration (from old DB to new)
add-migration UpdatedCoumnXXXX

you should review the code proposed and if you accept it just run

Update-database

and that's it.

This is if you added the column programmatically if you did it on the DB follow the previous suggestion from  @Shaun Vermaak
