The SlickUpload 6 RC has been released. You can check out the demos, or download the SlickUpload RC package.
This build has a few bug fixes, and full ASP.NET AJAX support, including running in UpdatePanels. We are considering this the final feature complete build of SlickUpload 6.
Our major thrust over the past month has been writing documentation and samples for SlickUpload 6. With SlickUpload 5, we supported .NET 1.1 and .NET 2.0, in VB and C#, making for 4 versions of each sample. ASP.NET AJAX and ASP.NET MVC only had 2 samples each, for a total of 25 or so samples. With SlickUpload 6, we dropped .NET 1.1 support, but added full samples for ASP.NET AJAX, MVC1, MVC2, and MVC3, and MVC3 Razor. This brings our sample count to ~144 (12 samples * 6 view environments * 2 languages).
The RC includes 4 samples (overview, client api, custom filename, and sqlclient), in all view engines and languages. We'll be releasing another build next week with all samples in all languages, followed by a final RTM later this month once samples and documentation are complete.
We're in the midst of writing the how-to documentation and guides, but we have completed the server reference. You can take a look at the docs on the new beta site.
As always, if you have any questions, don't hesitate to ask.
