Why does the keyword Entry squiggle in this statement: Entry.IntensityLevel.High?

In _EntryForm, the statement Entry.IntensityLevel.Low have a squiggle under Entry although we added the model directive @model Treehouse.FitnessFrog.Models.Entry at the beginning of _EntryForm.

What is the difference between @using Treehouse.FitnessFrog.Models AND @model Treehouse.FitnessFrog.Models.Entry? They both refer to the same resource except that @model points to Entry class specifically.

:point_right: The using directive can point to any namespace you may want to reference.

And you might have more than one using directive. In this case, it happens that elements of the same namespace as the model are being referenced, so the two are similar.

But the purpose is different, model defines the type of the passed in data model (and there can be only one), and using allows you to make references in the code to namespace elements without fully specifying them.

The "squiggle" is VS warning that it doesn't recognize the term "Entry". But once the using is added, it goes away.
