I'm a newbie about web services in VB.NET. I'm making a desktop application that will talk to JIRA (<http://www.atlassian.com/software/jira/>). They provided a REST api that I decided to use. The first step is to login which they say that...

**"To log in to JIRA, you need to POST a username and password in JSON format..."**

**{"username" : "admin", "password" : "admin"}**

**to this url...**

**<https://addressgoeshere>** (we are using https)

Can someone provide me a sample code to do this so I can have a guide and a good start?
