My background is Java and Javascript, so I bet I won't have to trouble to get hands on with C# itself, but I'm asking if somebody was in this situation at any time and could give me resources or recomendations for getting as fast as possible up and running with the .NET environment.
Thanks!
But, if you want to start quickly, you should start with imperative programming. Find a simple ui designer that works for you and add event handlers to controls. Take a look for some books from my former patron :

His advice on Ukrainian Microsoft Days is do not start as a senior, try a simple path first where code behavior is connected to the ui directy. Then understand some patterns that simplify your code and show declarative programing force.
