How to generate QR codes using library in .Net

I am planning to explore on QR code generation . I saw the google api开发者_如何学编程 http://chart.apis.google.com/chart?cht=qr&chs=75x75&chl=test and its pretty impressive. But it works only for URL's and small data's. So i am thinking about writing a .net app to generate the QR code. So any information on libraries to start with ,will be helpful.

Thanks,

It does not just work for URLs. You can put whatever text you want as an argument (just URL-encode it correctly). It also works for any data size that QR codes can support.
