Thanks for reaching out to us.
I work on Teleirk's Testing Tools team and can speak to our Test Studio application which does include native support for Telerik's ASP.NET AJAX, Silverlight and WPF controls. Test Studio includes a VS plug-in that allows you to work within the VS IDE and thus integrates with TFS for source control as well.
Telerik Test Studio is built on top of the Telerik Testing Framework, so tests previously created in CodedUI would need to be re-recorded using Test Studio (and vice versa). WIth Test Studio, you do have the ability to publish test list runs back into TFS attaching the results file to your build summary.
Additionally - Test Studio does indeed record browser actions as well as verifications - it's quite a robust solution. If your willing to download the trial - I'd be willing to take you on a tour and answer any additional questions you may have!
Hope this helps - and let me know if you'd like that tour!
