Not sure. I only noticed a day or so ago after Lluis (who has 0.7.9)
updated the boo binding to track core API, and we haven't yet had time
to investigate.

Now I look more closely at the message, it's not the same as the one I
was getting with 0.8.2. However, it's still nonsense. The offending
lines are.
for lib as ProjectReference in projectItems.GetAll[of ProjectReference] ():
for finfo as ProjectFile in projectItems.GetAll[of ProjectFile] ()

and it appears be be confused by the constraints on the generic types.
projectItems is a ProjectItemCollection. Relevant parts of the API

public class ProjectItemCollection: ProjectItemCollection<ProjectItem> {}
public class ProjectItemCollection<T>: ItemCollection<T>,
IItemListHandler where T: ProjectItem
    public IEnumerable<U> GetAll<U> () where U:T {}

So it appears to have not propagated the type of T into the
constraints of GetAll<U>.
