Hi guys! Im a beginner in C# beginning my journey towards a experienced programmer. I am creating a "application" in console that you'll see in my code below. I wanted to make a function to determine whether the user wants to log in or register and use it in main function to execute. But whenever I try to use it in main it does not find the function. The code is below and I'll post a picture with the error. Thank you for help guys and I'll hope i'll be to help in future!
