Need to disable auto-updating C# dependencies

I work in a secure environment so theres no internet connection, I can only manually transfer files to my machine from another machine with internet.

I’ve installed VSCode and the C# extension (via downloading the .visx), but the extension downloads other packages on first load which gives an error since theres no internet connection.

So every single time I start VSCode i’m greeted with an output window stating;

Updating C# dependencies...
...
Downloading package 'Mono Runtime (Linux / x64)' Failed at stage: downloadPackages
Error: getaddrinfo ENOTFOUND omnisharpdownload.blob.core.windows.net omnisharpdownload.blob.core.windows.net:443
...

Is there a way to stop the extension from attempting to update all the time so I don’t get greeted with the output window on each load?

I already have the following set;

update.channel : none,
extensions.autoUpdate: false

Even better, if there’s actually an alternative way to install the missing packages I would love to know!

Finally, even though i’m missing some packages I still use the C# extension for syntax highlighting etc.

Environment data

Platform: Linux, x86_64, Centos 7 VS Code version: 1.8.1 C# Extension version: 1.5.3 Offline machine (Internet connection is impossible)

Steps to reproduce

Fresh install the C# extension, disable your internet connection.

Expected behavior

Stop output window nagging on each fail, or update documentation on how to manually download missing packages.

@Greyze Thanks!

The issue with chmod is caused because you packaged the extension on Windows. That is actually why we have the exception on line 95. I will add more details about that. Thanks!
