Being as a core asp.net developer for 7 years and now working as a python/django from last 5-6 months; I can say every .net developer should change his development platform at least for couple of months, because it make you more mature developer.
.net is a good platform, but the real problem is you have to wait for MS to develop something. For example before "asp.net mvc" there is no option to use mvc in MS world.
For me learning python/django was not a big pain; but running them on ubuntu is a real pain; and i think this is true for every ms developer who want to change his platform.
On linux platform options are great and there are lots self motivated developers and fun projects which is not true in the case of MS.
One more thing - lots of start-ups work on the non ms platform. Once people talk about asp.net mvc they only talk about http://stackoverflow.com/, but we can find more successful example in rails, or django or php; which makes every ms developer on back-foot.
PS: I love c#, asp.net mvc and VS as a developer tools.
This is not correct. There were multiple MVC frameworks on top of ASP.NET years ago, including Monorail and FubuMVC and a lot more actually. All of them were open source. Some of them were quite good, actually.
Were you active there? Did you contribute something? Did you commit fixes/features. No, you did not. But of course you do contribute to the complaining.
