I have read up on two legged OAuth and understand the principals behind it - my question is specific to the DotNetOpenAuth library. Is there sample code or supporting documentation on how to use DotNetOpenAuth via two legged authentication? Three legged appears to be supported quite well and since two legged is simply a reduction in the number of steps I would assume this would be easy - so far, this isn't the case.
No, there's no samples of 2-legged OAuth with DotNetOpenAuth. If you're running into issues with doing it by just removing one leg from the existing samples, please describe the issues here: http://dotnetopenauth.net:8000/ticket/83 so they can be fixed.
