Roadmap

While we have provided links to all the versions we typically disable links to the older versions to stop people using older potentially buggy builds of the library. If you really want an old build you can either checkout the appropriate release from the releases directory in the dotNetRDF SVN Repository or Contact Us and ask for it.

You can find more details on the roadmap on the Ideas page and a much more detailed issue based roadmap in the Issue Tracker.
