What should be return type of method if it is returning a number?
A return type may be a primitive type like int, float, double, a reference type or void type(returns nothing).

What can legally be returned from a method?
Methods use the return operator to return a value. Any method that is not declared void must contain a return statement. The data type of the value returned by the return statement must match the data type that the method claims to return; you can’t return an Object from a method declared to return an integer.
Can a class return itself?
A class will often return an instance of itself from what is sometimes called a “factory” method. In Java or C++ (etc) this would usually be a public static method, e.g. you would call it directly on the class rather than on an instance of a class.

Is it a good approach to call return inside using..?
If C# had gotostatement -are you done laughing yet? good- then instead of return you could gototo after the closing brace, without returning. Logically, scopewould still be disposed, but you’ve just put gotoin C# so who cares about logic at that stage. – SuperbestSep 1 ’12 at 2:03 C# has goto. – Jake T.Mar 13 ’15 at 16:09
Can a class return an object of itself?

What is the purpose of ” return await ” in C #?
If you won’t use return await you could ruin your stack trace while debugging or when it’s printed in the logs on exceptions. When you return the task, the method fulfilled its purpose and it’s out of the call stack. When you use return await you’re leaving it in the call stack.
When to call stack when not using await?
Call stack when not using await: A awaiting the task from C, which B has returned. Making the otherwise simple “thunk” method async creates an async state machine in memory whereas the non-async one doesn’t.
