Description Charles Petzold 2017-11-08 19:01:27 UTC
The following program contains a class named TestClass that defines two attached bindable properties, SimpleProp of type string, and CollectionProp of type IList<string>:


The MainPage.xaml file sets these properties in two Buttons using property-element syntax, and the Clicked events show their contents.

As is, the program works, but CollectionProp is empty. When the contents of CollectionProp in MainPage.xaml are uncommented, a XAML compilation error of "Property CollectionProp not found" results. When XAML compilation is turned off, then the contents of the page do not appear.

Should be fixed in 2.6.0-pre1. Thanks!
