JSS REST API C# example?

[chelm]

Does anyone have working JSS REST API code in c#? I am trying to write an application that can grab basic computer information but I cannot find any good examples of C# and REST API.

If you have any sample code, sharing is greatly appreciated.

Thanks.

Edit:
I figured it out.

[Graeme]

How about sharing. I would be interested too :-)

Regards
Graeme

@Graeme Sorry it took so long, for some reason I never saw your request.

@Graeme You are welcome. I actually had to update it last week to use TLS 1.2 explicitly because we upgraded to 10.8. Here is the new code:
