Yeah, so some of my friends asked me why I am not using a twitter library instead of calling the api directly. Yeah, I'm wondering that to. Seriously, the reason why I am doing that is that .net libraries to call out to twitter that I tried under VS 2008, did not work with Windows Azure. These libraries seemed to generate a security exception. Given azure's security requirements being a little more than regular asp.net, I decided to just drop the search for a library and make my calls on my own. Not sure if its a good decision or not, but its what I did.
PS. I hear that Full Trust and Native Code support are coming to Azure.
