Disagree. I would argue Java is more of a choice for "Enterprise".

Also, would you please define the scope of "enterprise".

If you mean "enterprise" as someone who want consistent and predictable management and productivity, then sure .NET is "enterprisy", because instead of a dragon they want a fossil.

But if you mean "enterprise" as they want to sell their core product, and sometimes that pushes to high developmental velocity with multiple development team to tackle on a feature, then .NET is evolving fast enough that it is not so considered "enterprisy".

Heck, even Ruby on Rails would replace .NET for that, especially when you consider the e-commerce scene that is either Ruby or PHP (Wordpress).

Just look at C# and its incredible language revision every year.
