Can't bind to some objects in WPF using Expression Blend

I create a new Window and try to set my Class FooService as DataContext property. But in the "Select Object" dialog I can only find some of the classes but not the FooService.

Any Idea if there are any requirements for classes to be listed in that dialog?

Does FooService have a public parameter-less constructor? If not, Blend won't see it.

You need to add the appropriate namespace to the list of XML namespaces in the XAML file for the Window.

For example, if your FooService class had a namespace of "Services" you would add an xmlns declaration like so:

<Window ...
        xmlns:services="clr-namespace:Services"
        ... />

or (if it's in a different project that you have referenced)

xmlns:services="clr-namespace:Services;assembly=Services"

Assuming that project's name is "Services".
