This is the 4th Iteration of the Microformat.net project.
This release will contains many fixes to the current implementation and a lot of unit tests based on the tests on Microformat.org
The API has remained fairly static, but the XML Parser has completly changed.
A new windows forms based reference application is included. This takes a WebRequest Response Stream as input and returns a list of valid micorformats.
Please let me know of any issues you encounter so I can resolve them ASAP.
I have also provided a sample App.Config that I will maintain with any changes to the specs.
