X509CertificateAuthenticationProvider does not provide a way to specify IMsalHttpClientFactory

[SPWizard01]

Category

• [x] Bug

Describe the bug

When using this overload https://github.com/pnp/pnpcore/blob/dc8dd2d7536a8d65f8ca3fd5227835cd5188a4b8/src/sdk/PnP.Core.Auth/Confidential/X509CertificateAuthenticationProvider.cs#L89 token acquisition for Client App will fail because confidentialClientApplication has not been built

Steps to reproduce

        services.AddPnPCore(options =>
        {

            //var defProvider = new X509CertificateAuthenticationProvider(LoggerFactory.Create((b) => { }).CreateLogger<OAuthAuthenticationProvider>(), new SimpleHttpClientFactory());
            //defProvider.TenantId = tenantId;
            //defProvider.ClientId = clientId;
            //defProvider.Certificate = GetCertificateFromStore(certThumbprint);
            //this will not work to acquire token
            //options.DefaultAuthenticationProvider = defProvider;
            options.DefaultAuthenticationProvider = new X509CertificateAuthenticationProvider(clientId, tenantId, GetCertificateFromStore(certThumbprint)); //does not work behind a corporate proxy as IMsalHttpClientFactory is always null
        });

Expected behavior

Expected behavior is to be able to initialize this provider with IMsalHttpClientFactory, reasoning being behind a corporate proxy, I need to specify custom HttpClientHandler (with Proxy).

Environment details (development & target environment)

• SDK version: 1.13.0
• OS: [e.g. Windows 11
• SDK used in: Console App
• Framework: .NET Core v8.x
• Browser(s): Latest Edge
• Tooling: Visual Studio 2022

Additional context

I was not able to find a suitable constructor for X509CertificateAuthenticationProvider so that I can provide certificate, tenantId, clientId, and a custom IMsalHttpClientFactory. Maybe I am doing something wrong.

Workaround is to of course create your own implementation of OAuthAuthenticationProvider
