Failed to start hello world program in c # console application

Question

I am learning C # and running the hello world program for a console application. When I start using f5, the console appears and disappears immediately.

using System; namespace CSharpConsoleApps { class Program { static void Main() { Console.WriteLine("hello c sharp world "); } } } 

Below is the message displayed on the output

Answer 1

Your program runs successfully, but the console closes immediately.

To prevent this, use Ctrl+F5 instead of F5 .

Answer 2

It works exactly as you said!

Basically, this code simply says "show this line of text." So, once this is done, nothing else will be done, it will stop working.

Try to add

 Console.ReadKey(); 

And run it again

Answer 3

Computers do exactly what they programmed. In this case, the source code did not force the computer to wait for input from the user until it terminated. So, the computer followed the instructions as they were presented and normally completed the program.

You may try:

 namespace CSharpConsoleApps { class Program { static void Main() { Console.WriteLine("hello c sharp world "); Console.ReadLine(); } } } 

And run it again. The computer will wait for you to press ENTER before closing the console window.

Answer 4

Starting Visual Studio as an administrator.
