That's too bad, because there are tons of sharp .NET devs who despise the concept of "magic" (and no, ORMs are not magic, and Entity Framework is fantastic) and who understand the abstractions that .NET offers. I would hesitate to write off all .NET enthusiasts as clueless less-than-hackers.
(disclaimer: Microsoft employee, nothing to do with .NET though)
XNA is the example I always use. You can use XNA and make games without understanding anything about the graphics card but you can also dig in and write your own shaders and basically go however deep you want to/need to.
There are some things in .NET that do seem kinda magic, and razor is one of them. Not because it's a templating engine but just in how lightweight it is and how surprisingly decent intellisense can be with it. Most templating engines feel so verbose and ugly after working with razor.
Entity Framework is also a really nice ORM for most small-mid sized projects... If you're really stuck on using a strongly-typed environment I will say that C# is one of the better ones and would choose it any day over Java (and a lot of others). My issue with many .Net and Java projects is that a lot of "enterprise" design patterns are used when they are more in the way than helpful. Abstractions are used which only improves testing or portability, but neither testing or portability are used. But this is more of a design choice from the developers than the languages/platform used.
I also disagree with your reference to .Net/C# not having a large ecosystem... There are a lot of tools for C# out there, most open-source and easily available via Nuget. Not to mention that Stack Overflow has authoritative answers to almost anything you could need with .Net or C# and has MS employees as regulars to offer support.
This is from someone who doesn't even write much C# any longer (still supporting two legacy apps in C#), and does most of his development being deployed to Linux servers.
For me, the web development was too magic, way more so than RoR. I got an acquaintance that only do .Net. And he harps about how .Net got Razor and data base represented as object unlike open source. When I pointed out that Razor was just a template engine and that database thing is just ORM which many other MVC frameworks have he just didn't get it. He didn't get it's a template engine nor does he understand that it's an ORM. Magic! I also tried some .Net dev, and it's very magic in term of abstraction. The VisualStudio IDE is amazing and C# seems like a much better language than Java. But the ecosystem isn't as rich, Apache such an awesome organization but Oracle is very pushy.
The downsize for me is big, ecosystem. Most of the open source projects play very well together, C# is a newbie, I rather wait for it to mature within the open source space (including books and tutorials).
