JIRA, REST and .NET

I haven't seen much in the way of .NET code for talking to JIRA via REST so I thought I'd post some code from a spike I've been fooling around with.

In this example I'm deserializing JSON into known objects - that I created earlier using Visual Studio's EDIT > Paste Special > Paste JSON As Classes command - but you could just go with dynamic objects if you know the properties you want (though that's slower of course).
