WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

[ERROR] Error: Failed to start OmniSharp

VSCode 1.1.0
Installed plugin from Asset Store
Unity 5.3.4f1
Installed Latest Mono from their website.

Any ideas? I don't know how to even start debugging this.

Probably Omnisharp's fault. Keeping this here in case someone else needs help with it.

Looks like Omnisharp is no longer included by default since 1.1.x version of VSCode
I solved this issue by installing a new extension, based on Omnisharp.
Do the trick by hitting F1 inside VSCode and typing >ext install c#
https://marketplace.visualstudio.com/items?itemName=ms-vscode.csharp
There are several changes that impact .NET Core SDK.
I suggest users to read carefully what reported in the extension page.
