My friend Luke Smith and I for the last month have been working on a new .Net wrapper for Windows Live, which we have called LiveNet. You might be thinking "what's the difference between that and Windows Live Tools", and the answer is simple, a fair bit. Windows Live Tools has what you need for Windows Live ID web authentication, Silverlight Streaming and Contacts control, which we don't do anything with. Now at this point, I would just like to say that the Contacts control is the embedded object, whereas what LiveNet will [eventually] have is from Windows Live Data.
We have made this a .Net 2.0 wrapper, so it can be used with any web application that is 2.0 or above and at the moment we have only implemented the Live Photos API into the wrapper. So what does this mean? It means that we have built a set of classes that will allow you to interact with the Live Photos API without having to worry about any of the back end goings on. I shall go into more detail with some examples in just a moment.
LiveNet is an opensource project that we have hosted on CodePlex, so feel free to check out the source code if you want to see what we're doing under the hood.
Version 0.1 is now ready for you:
