My opinion is that the day when C# will compile to native (on any platform), the C# developer interest in D will drop instantly.
I do write a commerical project in C#. But I have an opposite feeling: The day D will easily compile to Javascript and be able to fully interface with it, my wish to use C# will drop pretty much instantly. I'm not even sure I would choose C# over -BetterC D!
It can already compile to Javascript using LDC/Emscripten, which is impressive, but you cannot interface with its strings and classes without glue code, except perhaps with some trickery. I have already tried doing some but so far for no avail.
And that's not to say that C# would be a bad language. I didn't hesistate to pick it over writing Javascript directly, and I don't think Java or Python would be superior for my tastes either. But it still isn't even a close match against D.
First, C# feels like it's hiding details from me, it kind of wants to maintain an ivory tower illusion. It's very hard, if possible at all, to control memory management. Libraries often feel like they're dependant on IDE (Visual Studio), not just the language.
Second, iterating in C# feels last-century standard. I like LINQ, but it still is like Phobos with only forward ranges, strange names and no thought put on avoiding needless heap allocations. And it's foreach loop can't iterate by ref, which means I often tend to iterate as if I was using C.
Third, expressive power suffers alot from lack of powerful templates, Voldemort types and var keyword being much more constrained in use than auto.
