Things are moving fast. Yesterday I released an early first version of Viddler.Net, a wrapper for the Viddle API. Today I was able to post an updated version to Codeplex, which seems more suitable for managing this project than my own blog. The updated version uses HTTP POST instead of GET and includes one extra implemented method to upload videos.
