Quick Fix (Ctrl + . ) Issue - Doesn't show required namespaces

Environment data

.NET Command Line Tools (2.0.0)

Product Information:
Version:            2.0.0
Commit SHA-1 hash:  cdcd1928c9

Runtime Environment:
 OS Name:     Windows
 OS Version:  6.1.7601
 OS Platform: Windows
 RID:         win7-x64

Base Path:   C:\Program Files\dotnet\sdk\2.0.0\
Microsoft .NET Core Shared Framework Host
Version  : 2.0.0
Build    : e8b8861ac7faf042c87a5c2f9f2d04c98b69f28d

VS Code version: 1.9.1 C# Extension version: 1.7.0

Steps to reproduce

Install NET Core SDK 2.0 Create angular project using dotnet core cli ( dotnet new angular ) Open project in Visual Studio Code 1.9.1 Install C# and C# extensions Start Omni sharp if not already started

C# Intelligence works in Visual Studio Code. Quck Fix (Ctrl + .) doesn’t work, It doesn’t show required namespaces after hitting (Ctrl + .)

Expected behavior

Quck Fix (Ctrl + .) should show required/missing namespaces after hitting (Ctrl + .) For ex.

public ICollection<Project> Projects { get; set; }

When cursor is on ICollection keyword, if you will press Ctrl + .
Quick Fix should show “using System.Collections”

Actual behavior

After hitting (Ctrl + .), Quck Fix doesn’t show required namespace suggestion. Build is successful. OmniSharp is also running fine. C# Intelligence is working fine. No error in problem pane

Note

I am behind the proxy.

Update: I have now also tested this on Fedora 28 with .Net Core SDK 2.2.103. Same problem persists, i.e. no suggestions for adding namespaces for missing types.

@cartermp The issue is still persisting in VSCode 1.73.0!
