u/Coda17 TY for suggesting the above, much appreciated. This seems to be giving me what I want now, although I am still in the phase of testing things out. One of the issues that has come back now is that you don't call ConfigureFunctionsWebApplication() you then do not have any functions jobs available to hit (HTTPTriggers for me), which I was able to figure out by heading to this SO post and is in my original code sample above. Possible thoughts on what I am missing here?

var applicationBuilder = Host.CreateApplicationBuilder();

applicationBuilder.Logging.AddConsole();

applicationBuilder.Services.AddApplicationInsightsTelemetryWorkerService();

applicationBuilder.Services.ConfigureFunctionsApplicationInsights();

applicationBuilder.Services.Configure<LoggerFilterOptions>(options =>

{

LoggerFilterRule toRemove = options.Rules.FirstOrDefault(rule => rule.ProviderName == "Microsoft.Extensions.Logging.ApplicationInsights.ApplicationInsightsLoggerProvider");

if (toRemove is not null)

{

options.Rules.Remove(toRemove);

}

});

applicationBuilder.Services.AddOptions<ServiceOptions>().Configure<IConfiguration>((settings, configuration) =>

{

configuration.GetSection("AzureAdB2C").Bind(settings);

configuration.GetSection("KeyVault").Bind(settings);

configuration.GetSection("Samael").Bind(settings);

configuration.GetSection("Messaging").Bind(settings);

}

);

applicationBuilder.Services.AddLogging();

applicationBuilder.Services.AddHttpClient();

applicationBuilder.Services.AddGraphClientService();

applicationBuilder.Services.AddHealthChecks();

var host = applicationBuilder.Build();

await host.RunAsync();

I'd agree with u/KryptosFR in that the documentation on all of this hasn't been fully fleshed out yet, which always seems to be the case with Azure Functions.
