Xceed is poised to launch Xceed Upload for Silverlight, its offering in support of Microsoft's promising new Silverlight technology. Slated for release in May or June 2008, Xceed Upload for Silverlight provides programmers with HTTP upload capabilities for C# and VB.NET development using Silverlight. Whether client software needs to upload single files, groups of files, or strings to Web servers, Xceed Upload for Silverlight makes implementation fast and easy. In batch mode, file transfer is deferred, letting the application gather data from different sources, such as form controls, performing the actual transfer when it is ready. Uploads are asynchronous for optimum performance, so the client software remains responsive throughout the operation.
