Is C# actually just a copy of Java? Also, is it worth learning at all?

Answer 1

C# is very similar to Java, but being a "copy" is an overstatement. In many things it is better designed, as its creators specifically tried to do things right what Java did wrong. If you develop for Windows / Microsoft platform, then C# is a great choice. But now you can also use it on other OS (mac, linux) with the new versions of dotnet.
