Been looking for some powerful software tools that I can produce rich .NET reports with WPF and Silverlight for a codeplex project I am working on (more details to follow soon). Over the years I have leveraged Telerik for their ASP.NET components while producing a site for Avtrak and been impressed with the RAD features and results – max impact with minimum effort. They have a nice WPF and SL toolset here that is powerful. Their documentation and support are excellent as well. Will keep you posted on the visualizations I come up with in WPF. This next gen toolset is going to be fun to work with.
