Detailed repro steps so we can see the same problem

1. When you have some unknwon package in the project an restore it just prints this:

Restoring NuGet packages...
NuGet package restore failed.
Time Elapsed: 00:00:02.7078836
========== Finished ==========

Yes, there is an error in the error list, but when build happens it does print errors in the output along with adding errors to Error list, but restore does not - it is inconsistent. Also, very often i have error list hidden with Output pane on top (active when docked) and i have to do extra clicks to go to error list (if will remember that error might be there at the moment..). I don't want to "think", but see it immediately ...

Other suggested things

Verbose Logs

Please include verbose logs (NuGet.exe -verbosity detailed | dotnet.exe --verbosity diag | etc...)

Sample Project

Very helpful if you can zip a project and paste into this issue!

This is similar to #5412

I think we should consider bringing the output window details back.

yes #5412 looks exactly what i meant :).

@anangaur - c# compilation shows errors in the output window and error list. should we do the same? can you please do a quick review and give your suggestion?
Or should we show the error window, every time?

(btw showing/poping error window or other tool windows everytime is annoying and this pattern is avoided in other places in core and web project system)

The above is a more general case, so going with that one.

Let me know if these are different requests, but it seems like the root cause of both is that NuGet isn't writing errors to the output pane.
