> C# is a nightmare of language identities - a jack of all trades, master of none, choose your dialect language.
I honestly have no idea where you would get this idea from. C# is a pretty opinionated language and it's worst faults all come from version 1.0 where it was mostly a clone of Java. They've been very carefully undoing that for years now.
It's a far more comfortable and strict language now than before.
I can see where he's coming from. For example, `dynamic` was initially introduced to support COM interop when Office add-in functionality was introduced. Should I use it in my web API? I can, but I probably shouldn't.
`.ConfigureAwait(bool)` is another where it is relevant, but only in some contexts.
This is precisely because the language itself operates in many runtime scenarios.
