• VSCode Version: 1.0.0
• OS Version: Kubuntu 16.04

Steps to Reproduce:

1. Install C# extension.
2. Try to edit an existing C# project, already containing a .csproj file in the folder.

I am also getting a very similar error, but I'm not sure if its the same cause.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value HKLM\Software\Microsoft\Fusion!EnableLog 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

The two INFO lines come up immediately, and the ERROR comes up about 60 seconds afterwards.

I has installed VSCode a few days ago, and the OmniSharp extension, and created a simple test project using .Net code - hello world basically. Everything went fine.

Then yesterday I then downloaded a project of mine from Github, and tried to create a project.json file for it (no idea if this would work). Once I got a valid project.json file I started to get the above error. I then returned to the Test project and am now getting this error on that project too.

If I look in the extensions\ms-vscode.csharp-0.3.7\bin\packages directory I have Newtonsoft.Json version 7.0.1, but not 6.0.0.0 as mentioned in the error message above.

Hope this helps.
