Intellisense not working with rc4

[perlun]

Environment data

dotnet --info output:

$ dotnet --info
.NET Command Line Tools (1.0.0-rc4-004711)

Product Information:
 Version:            1.0.0-rc4-004711
 Commit SHA-1 hash:  3eee54e4f9

Runtime Environment:
 OS Name:     Mac OS X
 OS Version:  10.12
 OS Platform: Darwin
 RID:         osx.10.12-x64
 Base Path:   /usr/local/share/dotnet/sdk/1.0.0-rc4-004711

VS Code version: 1.8.1
C# Extension version: 1.7.0-beta1 (installed to try and see if it helped, which it didn't)

Steps to reproduce

Opening a .NET Core project with a .csproj and .sln file.

Expected behavior

Intellisense.

Actual behavior

Intellisense broken. All I get is the flame icon saying "Switch projects". When I do, it runs for a while and goes back to the same mode.

Here is the output:

(Note: it used to work for me, but stopped when I upgraded the dotnet cli tools to rc4)

@perlun: Have you run dotnet restore? Currently, auto-restore for package references (#770) is not implemented for .csproj yet.

@DustinCampbell yep, but doesn't help. Here is the OmniSharp output right now:

I uninstalled rc4 and went back to preview4 instead, using this link: https://github.com/dotnet/core/blob/master/release-notes/preview4-download.md

Works like a charm now... Closing, someone else can reopen if they feel like digging more into this.
