Hi all,

I am developing a new project integration for the Visual Studio and I have
two issues for which I don't seem to find any explanation in the
documentation.

1. All my project items that are files (i.e. not the folder items) get an
additional small red icon in the Solution explorer. I suppose this is because
I answer with unexpected value or don't answer at all at some GetProperty on
these Hierarchy nodes. But I don't know which property causes this. The files
are all existing on the disk.

2. If I open a solution which only contains one project, the solution root
element is not displayed in the Solution Explorer. The root of the solution
explorer is the project node itself (whereas I would expect the Project node
to have a parent and that would be the solution node). Same as before, I
suppose I don't send back the correct answer to some property but I don't
find which this property could be.
If I add a project to the solution (also one project of the same type) then
the solution node appears correctly as parent of the two project nodes.

Please advise me if you have any information that might help.

Thanks in advance!
Gabriel.
