What does XamlCheckProcessRequirements do?

[amtopel]

I'm wondering what XamlCheckProcessRequirements, which precedes the message loop inside the XAML-generated main function, does. Like what does it look for, and what does it do on failure?

Also, I've come across an example of a custom main function that removes that function call entirely. Is that okay to do?

IIRC, it basically does nothing. But what it does is put a crash point into main if, for some reason, the process starts without bootstrapping the Windows App Runtime. It will cause a crash in main which is easy to diagnose rather than some less obvious failure when trying to instantiate a Windows Runtime object.

Okay, cool. Thanks for the info.
