Problems list dominated by unused usings

Makes it hard to see real problems. Can we downgrade this thing so it doesn't show up by default in the list of problems?

This is a duplicate of #315 but I'm going to keep it on the backlog.

Sadly, there is no way to downgrade a diagnostic such that it's completely hidden in the Problems window today. We could make it a "hint", but that only hides the squiggle in the editor and leaves it in the Problems window, which isn't what we want.

I have microsoft/vscode#20219 open to get an API that'll allow us to have a better more VS-like experience here.

Maybe we can just remove them as problems for now in general? It's just noise at this point. When we get the new API then we can improve the experience all up.

Maybe, I'm not super-keen on the user experience of having no presentation in the editor at all for this remove unnecessary usings. That said, maybe you're right and it's worth it to hide for now and bring back in it's full glory later. 😄

I'll take a look for 1.8.

[davidfowl]

Keep the code fix but remove the info 😄

I was so looking forward to this in 1.8... (

Sorry about this. I had to slip this one to get 1.8 out for some important debugger changes. Fixing this is on my list after restoring test support for csproj .NET Core projects.
