NeatUpload ™ is an ASP.NET component that allows developers to stream uploaded files to storage (filesystem or database) and allows users to monitor upload progress. It is open source and works under Mono's XSP/mod_mono as well as Microsoft's ASP.NET implementation. In 2010, after developing NeatUpload for 5 years, I moved on to other endeavors. The project is now hosted at CodePlex under the stewardship of Joe Audette I no longer use the code myself and haven't looked at it since 2010, so I am no longer qualified to answer any questions regarding it. Please refer to neatupload.codeplex.com for support.
