Note: This is happening, but it's a lot of work. The work is being tracked in https://github.com/OmniSharp/omnisharp-vscode/projects/2.

@DustinCampbell thanks for the response. I'd love to contribute any way I can

Thanks! I got much it working today.

There's a new v1.5-future-preview1 release that adds initial support for MSBuild-based .NET Core projects.

Note that there's still a lot to do to fill out the experience, but this should unblock you.
