Not really. I've written a bit of Go and a lot of C#, and can tell you from my experience that they are very different tools. C# is a very feature rich language like C++, while avoiding the majority of the 'gotchas' in C++ (in obvious areas such as memory management). Generic types, Abstract Classes, LINQ etc. all can be very productive if you know how/when to use them.
Golang is much more minimal. It does have some very nice concurrency features that could be a big win for some users. C# is fine at concurrency, but Golang's way of integrating it into the language is definitely more streamlined.
IMO pick the best tool for the job. In many cases, large enterprise pieces of software that want the mature tooling of C# will benefit from .NET Native. /rant
