I feel the opposite. It is one of the genuinely competent languages out there, if you're the kind of person that isn't upset about it being a "kitchen sink". Instead, I feel like the ecosystem, community and reputation hold it back. There are nowhere as many useful and popular packages to reach for as Python for example. Unity3D always lags behind in runtime and language version and had amazingly bad package management -- this further hamstrung C#, because the language is never used in a vacuum.
