Compiler warnings. Warnings. They’re not errors, only warnings. You can just overlook and forget them, right? Well, I hope you aren’t.
“But even the standard code done by Microsoft throws warnings!”, you could say. And that’s true, but that’s not your code, it’s Microsoft’s. If a functionality you’re using breaks because they didn’t care about their warnings, you can open a support request and it’s Microsoft’s job to fix it. If your code breaks some functionality because you didn’t care about a warning, it’s your job to fix it, and your customer will want it as fast as you’d want Microsoft to fix their error.
That’s why we should be warned about warnings (badum tss).
