ExecutionProviderCatalog.GetDefault() on Copilot PC

Hi,

I am getting an exception on Copilot PC while using WindowsML sample code in release/experimental branch.

Here is the sample code
EnvironmentCreationOptions envOptions = new()
{
logId = "ResnetBuildDemo",
logLevel = OrtLoggingLevel.ORT_LOGGING_LEVEL_ERROR
};

        // Pass the options by reference to CreateInstanceWithOptions
        OrtEnv ortEnv = OrtEnv.CreateInstanceWithOptions(ref envOptions);

        // Use WinML to download and register Execution Providers

        **var catalog = ExecutionProviderCatalog.GetDefault();**
        var registeredProviders = await catalog.EnsureAndRegisterAllAsync();

"ExecutionProviderCatalog.GetDefault()" is throwing an exception.

Here is the exception details
"Error in cpuinfo: Unknown chip model name 'Snapdragon(R) X Elite - X1E78100 - Qualcomm(R) Oryon(TM) CPU'.
Please add new Windows on Arm SoC/chip support to arm/windows/init.c!"

Unhandled exception. System.Runtime.InteropServices.COMException (0x80070490)

This is a copilot PC. Is there something I need to install to run this ResnetBuildDemoCS code?

Thanks,
Rajiv

Start with the ResnetBuildDemoCS sample and the ExecutionProviderCatalog.GetDefault() call, then reproduce the failure on a Copilot PC. Trace the reported cpuinfo error for the Snapdragon X Elite model and determine whether the sample needs an installation step or support changes. Done means the cause and required resolution are verified.
