Just got my wave sandbox invite today. Does anyone know of a .NET library for google wave? (client and server) I'm a c# programmer, not very familiar with the language that the Google samples are written in. It's very existing can't wait to write something for it.
I'm porting the Robot API to ASP.NET if that's what you're after.
Eventually the code will be hosted on this Google Code project - but there's nothing there yet.
I've got as far as having most of the Java interfaces ported and I can deserialize the JSON, but I haven't done the serialization yet. I probably won't be able to make much progress in the next couple of weeks, but after that I should be able to get back to it. If you're interested in what I've got so far I can try to clean it up a little bit and put it up on the project this weekend. It's really been spiking so far, so I have a shameful lack of tests :(
Note that the sandbox doesn't allow robots to run other than on AppEngine at the moment - if you know any Java at all you might want to follow the Java Robot Tutorial to get an idea of the kind of thing you'll be able to do. (I'm hoping to be able to test my port internally so that when the public version launches the ability to connect to non-AppEngine robots, with any luck I'll be ready.)
If you're not talking about the Robot API, could you give more details of what you're after? I haven't looked at any of the other APIs available (or coming) but I believe the gadgets are basically JavaScript.
(Btw, I'm [email protected] if you want to get in touch. I don't look at the sandbox very often though.)
I've done a quick implementation using BING Apis and Skeet's API - http://amazedsaint.blogspot.com/2009/09/bingybot-google-wave-bot-written-in.html
