I don't find this at all. Most of the .Net tools and things I use are free and open source: NHibernate, Rhino.Mocks, NUnit, CruiseControl.Net, NAnt, Wix, Windsor, Quartz, log4net.
Admittedly good profilers aren't free, and nor is the obligatory ReSharper. But for the most part all the extra utilities and things I've needed are readily available and open source.
