All these courses in C# - do we really need them?

Question

Correct me if I am wrong, but do I really need to know all these courses about C#, to write a good app? Or it is more just like LEGO blocs, that may be needed to build something?
I know that C# is not just about "console.writeline" or similiar. It is very big language, so topics of this C# courses is more like - Dude! you may gonna need this?!
Once again - correct me if I am wrong!? :)

Answer 1

C# is very useful if you want to utilize the .NET framework, which has a plethora of utilities. My personal favorite is text-to-speech. Also, C# is good for creating Windows applications (especially with Visual Studio).

Answer 2

I think you should know more than this, because app gives you only basic knowledge

Answer 3

yes, I know that there is some big benefits for C# as a language, but my question was a little bit different. I wanted fo know about programming (it can be C++, or C# ir other) as a concept, as a abstract idea...

Answer 4

Hmm. The or a idea of C# was/is to make the semantic and syntax more human like und less machine like. Same reason why we abstract machine language to assembler or higher...or?
