What is "resources.pri"?

[Mike_D]

Testing 2025R1 with a Windows EXE build, and there’s a new (to me) 19MB file called “resources.pri” file.

What is it?

[brian_franco]

should be for the Xaml UI elements?
I know UWP apps include this

@brian_franco

Oh, that makes sense.

I was hoping that using WebView2 via DesktopXAMLContainer would be quite a bit smaller (vs. using the Chromium browser).

I guess 19MB is better than XXXMB , but I wonder if all of that 19MB is needed? That’s a lot of bytes!

Ok, this is weird:

I can delete the file resources.pri entirely, and my WebView2/DesktopXAMLContainer app runs fine!

I wonder if this file is included in the build by mistake? Or perhaps simply not needed for WebView2?

(Testing on Windows 11 / ARM)

Your mileage may vary on this one, but resources.pri contains all the theming assets so removing this file will likely change the look of your app or worst case cause a crash.

It’s definitely not a mistake, a good example would be to add a XAML TextBox control to see what it looks like with resources.pri available and without.
