I always have issue with the "enterprise" cop out that many .NET developers like to fall back on when attempting to explain their resistance to using non-MS libraries. It reminds me a lot of iPhone v Blackberry in "enterprise" and we all know who won that... At the end of the day, "enterprise" people go home and become "consumers". Google and Facebook aren't enterpise and serve billions of requests a day, but they are founded on OSS technology. What does enterprise besides expensive software with vendor lock-in? There is no guarantee that MS won't tire and move along either. At least with OSS like Nancy, you don't have to worry about MS sunsetting a product your company relies on. You can continue to develop it long after the project has died.
