# Page 299 - Treating warnings as errors
This section shows how to follow best practice and treat warnings as errors. But doing so means you must write extra code in common scenarios to fix all warnings that will now be treated as errors that prevent compilation during the build process.
So this section also shows how to disable some common warnings by adding extra code. The project is NOT designed to be run. The code in it is written only to illustrate some common warnings and how to disable them to allow a build.
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.
