There are new properties related to cloudfiles that are missing from the schema, for example, I need to provide a clsid for my IStorageProviderSearchHandlerFactory https://learn.microsoft.com/en-us/uwp/api/windows.storage.provider.istorageprovidersearchhandlerfactory?view=winrt-26100

Isn't IStorageProviderSearchHandlerFactory meant to be provided by the cloud provider?

https://learn.microsoft.com/en-us/windows/win32/cfapi/build-a-cloud-file-sync-engine#cloud-files-search

• Cloud storage providers can register a file search handler for their sync root, enabling them to contribute search results to File Explorer and Windows Search.
• Cloud storage providers register a search handler by setting the SearchHandlerFactory registry value under their sync root registry key to the CLSID of their COM local server object. This local server object implements the IStorageProviderSearchHandlerFactory interface.
• The IStorageProviderSearchHandlerFactory creates an implementation of IStorageProviderSearchHandler. This IStorageProviderSearchHandler implementation calls the cloud provider's search service to search files that might not be available locally on the device.

@DrusTheAxe yes I am the "cloud files provider", not sure how familiar you are with cfapi but the cloud files provider is the software running on the user's PC - the registry key they refer to is placed under the same key that desktop3:CloudFiles is already responsible for creating

I notice there are quite a few registry keys missing that OneDrive manually sets but aren't supported by the manifest, but for now the search handler is what I'm looking for

I wondered if that's a doc bug...but reviewing the schema implementation the only namespaces I see mentioning cloudfiles is desktop3 (~2017), cloudfiles (~2019) and cloudfiles2 (~2021) and none mention 'search'. I don't see how you can manifest this functionality.

@RDMacLachlan to rope in CloudFiles folks to determine if this is intentional, a bug in cloudfiles' MSIX support or there's an alternate mechanism for some reason.
