Commented Issue: Update package dialog hangs in VS2012 [2532]

I'm trying to update a package with large amount of files in content. After short period of time Package manager GUI hangs. Dialog "Updating" just freezes. I even can't scroll anything inside it. <br />It's a blocking issues. I just can't use VS2012 and updating packages.
Comments: I was able to repro this issue thanks @casquith for sharing the details. Repro: 1. Create new webapplication 2. Drop in a folder in webapplication (I had dropped in 9,377 Files, 2,360 Folders) 3. Turn on show all files 4. install a package Actual: - WalkDepthFirst traverses thru all the items that are not part of solution causing the issue - found that it could be fixed by only checking when child.GetProperty(__VSHPROPID.VSHPROPID_IsNonMemberItem) is false - this makes me think that this would also cause perf issue for folks who have projects with large number of items, or are trying to install on a solution with multiple large projects? Will create a separate issue to track it.
