Xceed launched Xceed Upload for Silverlight, the commercial offering in support of Microsoft's promising new Silverlight technology. The product is available now for purchase or as a fully functional 45-day trial on Xceed's website. Xceed Upload for Silverlight lets developers add upload capabilities to any Silverlight 2 Beta 1 application. All upload operations are asynchronous; as a result, the Web page hosting the Silverlight application remains perfectly responsive and usable throughout the transfer.
