New Post: Seeing ViewModel Properties when Binding

This is for the new Prism 4.2, but not an item to selected below.

I noticed there were some new features added in VS 2013 for XAML and binding. One was to be able to see the properties of item that was bound to the UI component. As an example, if I had a Person Class bound to a Grid with TextBlocks, I should be able to see properties (e.g. FirstName, LastName, etc.) in the XAML when typing <TextBlock Text={Binding ...

I thought with the new locator and features within would work with the new bits. It still works and will be displayed in the UI. I'm I missing something?

Thanks
