Great apps powered by ClickOnce
OTTO, the 2nd largest online retailer in the world, just went live with a very impressive ClickOnce-deployed WPF application which completely changes the online store as you know it. See http://www.otto.de/vista
This app also uses Windows CardSpace and Windows Communication Foundation (WCF), both .NET Framework 3.0 components and part of Windows Vista.
I love seeing ClickOnce being used in mainstream consumer oriented applications, and will be posting about these more often. And that's not just 'cause my team owns WPF Deployment and works closely with the ClickOnce team. Having had my share of munging around with MSIs, I think ClickOnce is by far the most superior application deployment technology out there for rich client apps on Windows. It provides a sophistocated update mechanism for your apps, taking the pain out of that process. If you haven't heard of it before, or aren't using it in your .NET apps, I think the apps above will make you reconsider.
