Why does F # warn me about ignoring the result

Question

I play with F #, and the compiler warns me if I do not use any result ( the same problem described here ). Since F # even has an “Ignore” function for this, it seems like it is somewhat important, but I really don't understand why - why does C # not care about it, but does F # do?

Answer 1

One fundamental difference between C # and F # is that in F # this whole expression (as opposed to a combination of expressions and statements). This includes things that are operations in C-style languages, such as control flow constructs.
