Answer 1

Often write games in C# and perspectives using .NET?

Often. There are prospects.

Engines other than Unity are used?

I know that Supergiant games use Monogame. The result is quite good.

Will it be possible to write a simple strategy in C#, something like crossout, and how long will it take?

Well, something like a crossout, with resources like gaijin, you will be able to do it in a couple of years.
A minimal prototype can be riveted in a couple of weeks, if you have the necessary skills - there are a lot of videos on youtube where a person saws a prototype of some game in a few days or a couple of weeks.
