c# Wordpress XMLRPC wrapper

An existing software uses JoeBlogs wrapper for WordPress XMLRPC [login to view URL] but during the latest WordPress updates some functionality is not working anymore. So I need an update or alternative to do at least the following typical operations from within my existing c# client to a WordPress Blog: * Login * GetUserBlogs * GetUsers * GetRoles * GetCategories * Create New Posts * Create New Pages (not working anymore) * GetPost * GetPage * GetRecentPosts * GetRecentPages * and the releated edit and delete functions * support of more blog management functions is an option and would be nice Very important is the CreateNewPages feature because somehow this is not working anymore.
