When you are writing your programs, you must remember that C# considers lowercase and uppercase characters as different. As a general rule, most C# commands start with a capital letter and continue with lower case letters. C# constants are usually written all in uppercase, while variables use a mix of upper and lower case letters.
As you can see in the above example, we changed the name of our method from Main to main, in which case the compiler displays an error and complains about our program not having a starting Main method.
