Latest OmniSharp beta as of now is 3.5.0-beta.2204 which seem to work with the latest .NET Core SDK.

Did this by setting "omnisharp.path": "latest" in VS Code’s setting.json.

I had this same problem with dotnet 2.1.602 – downgrading to 2.1.500 worked for me as well. Thanks @nhactung for the suggestion!

For those on linux mint or ubuntu: sudo apt-get install dotnet-sdk-2.1=2.1.500-1
