Help with setting up dependency injection

[kuromukira]

Here's my code sample, from what I understood at this documentation

// from StartUp.cs
....
services.AddPnPCore(options =>
{
	options.PnPContext.GraphFirst = true;
	options.PnPContext.GraphCanUseBeta = false;
	options.PnPContext.GraphAlwaysUseBeta = false;
	options.HttpRequests.UserAgent = "MyApiProject";

	options.Sites.Add("MySite", new PnPCoreSiteOptions()
	{
		SiteUrl = sharepointSiteUrl
	});
});
services.AddPnPCoreAuthentication(options =>
{
	options.Credentials.Configurations.Add("CertConfigName", new PnPCoreAuthenticationCredentialConfigurationOptions()
	{
		ClientId = sharepointClientId,
		TenantId = sharepointTenantId,
		X509Certificate = new PnPCoreAuthenticationX509CertificateOptions()
		{
			StoreName = StoreName.My,
			StoreLocation = StoreLocation.CurrentUser,
			Thumbprint = sharepointThumbprint
		}
	});
	options.Credentials.DefaultConfiguration = "CertConfigName";
	options.Sites.Add("MySite", new PnPCoreAuthenticationSiteOptions()
	{
		AuthenticationProviderName = "CertConfigName"
	});
});

// using in classes via dependency injection
public class MyClass(IPnPContextFactory pnpFactory)
{
	...
}

However, I get the exception: An exception was thrown while activating MyProject.MySharepointService -> PnP.Core.Services.PnPContextFactory -> λ:PnP.Core.Services.SharePointRestClient -> PnP.Core.Services.SharePointRestRetryHandler -> PnP.Core.Services.RateLimiter.

Additional information: I am using Autofac to populate my dependencies

At the end of SDK Basics / Getting started / Configuring the needed services there is an alternative setup that I used in my test application and it works fine with Dependency Injection. See below, I removed some code that set options and such but the options.DefaultAuthenticationProvider property is the interesting part:

var host = Host.CreateDefaultBuilder()
// Set environment to use
.UseEnvironment("demo") // you can eventually read it from environment variables
// Configure logging
.ConfigureServices((hostingContext, services) =>
{
  // Read the custom configuration from the appsettings.<environment>.json file
  var customSettings = new CustomSettings();
  hostingContext.Configuration.Bind("CustomSettings", customSettings);

  // Create an instance of the Interactive Authentication Provider
  var authenticationProvider = new InteractiveAuthenticationProvider(
                  customSettings.ClientId,
                  customSettings.TenantId,
                  customSettings.RedirectUri);

  // Add the PnP Core SDK services
  services
  .AddPnPCore(options => {
      options.DefaultAuthenticationProvider = authenticationProvider;
  });

In the application I just added the IPnPContextFactory as a parameter in the default constructor:

public class MyClass(IPnPContextFactory pnpContextFactory)
{
   // Do stuff
}

Thank you. I tried doing something similar, it works now.
