@ -81,7 +81,20 @@ So this section also shows how to disable some common warnings by adding extra c
For example, one warning is caused by the compiler thinking there could be a null dereference. To disable the warning, you therefore need to check for a `null` value *even though we know that can never actually happen* as explained in the note. That extra code check is pointless if you run the console app and expect it to work correctly.
In the next edition, I will add another note to explicitly tell the reader not to run the project. The project implementation is not written to actually function as a check if someone has entered their name because that's not the point of this section.
In the next edition, I will add another note to explicitly tell the reader not to run the project. The project implementation is not written to actually function as a check if someone has entered their name because that's not the point of this section. I will also simplify the code.
Current code:
```cs
if (name == null)
{
Console.WriteLine("You did not enter a name.");
return;
}
```
Code in next edition:
```cs
if (name == null) return; // must check for null to remove the warning
```
