ResourceLoader crashes upon upgrading to 1.1.1

[leduyquang753]

Describe the bug

With the default Windows app SDK version of 1.0.3 from the C++/WinRT WinUI 3 in desktop template, instantiating a ResourceLoader works and loads Strings/en-US/Resources.resw normally. After upgrading the SDK to 1.1.1, such an instantiation produces "an application internal exception" of impl::error_out_of_bounds and crashes the app.

Steps to reproduce the bug

1. Create an unpackaged C++/WinRT WinUI 3 in desktop app.
2. Create Strings/en-US/Resources.resw.
3. Upgrade Windows app SDK NuGet package to 1.1.1.
4. Insiantiate a ResourceLoader.
5. Debug the app.

Expected behavior

The ResourceLoader is instantiated successfully and the app can proceed.

Do you have the 1.1.1 runtimes installed? Think this is just another manifestation of #2592.

I did go to great lengths to get the latest runtime packages to install successfully, the output showed it managed to load the runtime package and it did go into the app code until the line that instantiated the ResourceLoader was reached.

Ah ok. Can you zip up/attach your sample project? (just drop the zip into this issue)

I just found out about ResourceLoader::GetForViewIndependentUse but it also throws 0x00000004 "The system cannot open the file", if I change the project to packaged it works.

Looking around about this error reveals a resolved issue from the PowerToys team #2583, I will see if that reveals something I am missing.

Indeed what I missed was that I was using "system MRT" with a class name of winrt::Windows::ApplicationModel::Resources::ResourceLoader, after changing to using MRTCore's winrt::Microsoft::Windows::ApplicationModel::Resources::ResourceLoader it can now run. I would suggest giving this a mention somewhere in the documentation, unless it's already been done and I have also missed it. 😅
