Hi aspfun,
How to complete "Advanced Precompile Settings" options?
I suggest you could do this:
1.In Visual Studio, open a web application project.
2.Right click the project name in Solution Explorer, and then choose Publish.
3.Select the Settings tab.
4.Expand File Publish Options, and then select Precompile during publishing.
5.Click Configure.
More details,you could refer to below article:
