VSTO deployment in Visual Studio 8 - Orcas
Hats off to VSTO (VS, ClickOnce) team! No more problems with CAS and prerequisites. You can deploy your VSTO solutions with ClickOnce with a couple of clicks - same as you would deploy Windows Forms application. I would post an example but it's really so simple that you don't need an example :) (you can check the example over at Paul's blog).
You can download Visual Studio 2008 beta 2 here.
