How to stop C# console applications from closing automatically?

My console applications on Visual Studio are closing automatically once the program finishes the execution. I'd like to "pause" the applications at the end of their execution so that I can easily check the output. How can I achieve that?

Update:

As of Visual Studio 2017, there's a built-in option in the IDE at:

Tools > Options > Debugging > Automatically close the console when debugging stops

Unchecking it will automatically pause the application at the end of the execution, allowing you the easily check its output without having to add extra code to your application.

There are two ways;
Console.ReadLine();


ReadLine() waits for ↩

or
Console.ReadKey();


ReadKey() waits for any key (except for modifier keys).
