By choosing "Update model in database" from the context menu when I right-click on the.edmx file, I'm attempting to update the model. But the contextual menu does not have this option; am I missing something?
The designer view opens when the.edmx file is opened.
There, if you click with your right mouse button, you have the choice to "Update model from database."
Additionally, the Model Browser window appears, and any entity there may be updated from the database by using the right mouse button.
