Use tool tip for information about dependencies node warnings

[taori]

In the past i remember the project tree would display a warning at dependencies and tell me what exactly is wrong with references, by hovering a node. However the tooltips which used to appear, to not appear any longer so i can't really see what's wrong with my project.

You can check out the repo which points to this: https://github.com/taori/Amusoft.VisualStudio.Extensions/blob/master/templateSources/WpfApplication/Company.Desktop.Application.sln

In order to reproduce the issue.

You will need to enable support for netcore sdk to run the .application.csproj, when attempting to reproduce it with VS 2017.9.2

This is the really confusing one. It tells me i have an issue but won't show me what it is.

@taori thanks for the report.

As I understand it, this is a difference between the old project system and this newer one. It's something that's on our radar and we are currently tracking in #2653. I agree that a tool tip seems like a good solution here. We will also consider including something in the error list.

What version of VS are you using?

@drewnoakes We are supposed to show errors/warnings from the assets file here in the tree and Error List. I'd check the assets file to see if the issue exists in there and we're not raising it.

I think i somewhere read that this is a temporary situation of netcore 3.0alpha being integrated in VS2017. However the idea to display those errors anyway should be a thing, which always works, since there appears to be some information available pointing out potential flaws. At least many issues i've encountered while upgrading my projects were at least pointed out as warnings in the error list, unlike this issue. Guess whatever the problem is, is unordinary.

489770dca0fc6d31ffb4d393dc2bf637cb3344a3 is the commit necessary to reproduce i think. In the meantime i've changed some project settings to make my project work and thus removed netstandard crosscompile entirely from WPF related projects.

Images above don't look right: if top level nodes have warning icons they should be propagated to all lower level nodes that have issues. If they are not it is a sign of some timing issue where nodes are out of sync with current state of the dependencies snapshot.

This is #3780.

Closing this as we have other issues tracking the outstanding issues covered here. We're actively working on fixes now.
