XAML - StaticResources in Collection Initializers

Question

I want to add a single model object that has been instantiated once in XAML, and add it to two different collections (in xaml). The following code renders fine in Blend's Design Time, but I get the following errors at run time: For "Post1" Object of type 'WpfBlog.Models.Tag' cannot be converted to type 'System.Collections.ObjectModel.ObservableCollection`1[WpfBlog.Models.Tag]'. Error at object 'WpfBlog.Admin' in markup file 'WpfBlog;component/Admin.xaml' Line XX Position YY. If I comment out "Post1", I'll get this error on "Post2" Cannot add element to property 'Tags', because the property can have only one child element if it uses an explicit collection tag. Error at object 'System.Windows.StaticResourceExtension' in markup file 'WpfBlog;component/Admin.xaml' Line AA Position BB. The following code compiles and runs fine, but two tags named "TDD" get created, so if I try to rename the tag, I have to do it for all of the posts, instead of just the one Tag object. Any ideas? I'd be able to ignore it and work around it if Blend didn't render it correctly, but it does!

Answer 1

I was able to avoid the problem by explicitly initializing a new collection within the Tags property. Something like this: Obviously, this is only possible if you allow your Tags property to be writable.
