title: What are the various "Build action" settings in Visual Studio project properties and what do they do?
body: <p>For the most part, you just take whatever Visual Studio sets it for you as a default... I'm referring to the <a href="https://docs.microsoft.com/en-us/visualstudio/ide/build-actions?view=vs-2019" rel="noreferrer">BuildAction</a> property for each file selected in Solution Explorer. There are a number of options and it's difficult to know what each one of them will do.</p>
