This might help you guys.(I've applied this to my Projects)

Here's the 3 easy steps.

1. Go to your Solution Explorer. Look for .edmx file (Usually found on root level)
2. Open that .edmx file, a Model Diagram window appears. Right click anywhere on that window and select "Update Model from Database". An Update Wizard window appears. Click Finish to update your model.
3. Save that .edmx file.

That's it. It will sync/refresh your Model base on the changes on your database.
