Here. These guys demonstrate not only a cool application of Managed C++, but also what a fabulous bridge that MC++ is between the unmanaged and managed worlds. Folks that haven't moved to VS.NET because they're doing C++ are *really* missing out.
Here. Aurigma has posted the beta for a COM to .NET wrapper generation tool that doesn't require the COM server to be registered, which is nice for hosted scenarios. It also generates the wrapper code for you to see and edit for your own purposes. Interesting.
Here. I just know that folks are going to need to be able to convert between VS.NET 2002 and 2003 projects and solutions for a while yet, so here's a free, extensible conversion tool to do the job.
Here. This article comes with the full source for hosting the WinForms Designers to enable form design in your own app. To my knowledge, none of this stuff is supported, but that doesn't make it any less cool!

Here. From Matthew Mastracci: I just released the fifth alpha version of my free, open-source .NET profiling application. It supports everything I've thrown at it so far (multi-threaded programs, NAnt, SWF apps) and is getting close to feature-complete.
It comes with a basic VS.NET add-in that lets you profile from DevStudio. There is a complete source package on the downloads page for those who are interested in learning how a profiler works, or just want to tinker.
