Azure Function host.json 设置不起作用

解决方案：https://github.com/Azure/azure-functions-servicebus-extension/issues/81#issuecomment-1139175220

    public class Startup : FunctionsStartup
    {
        public override void Configure(IFunctionsHostBuilder builder)
        {
            var tempServices = builder.Services.BuildServiceProvider();
            var azureFuncConfig = tempServices.GetService<IConfiguration>();

            var config = new ConfigurationBuilder()
               .AddConfiguration(azureFuncConfig) // if you commented this line hots.json settings will be overridden to defaults 
               .AddEnvironmentVariables()
               .Build();

            builder.Services.AddSingleton<IConfiguration>(config);
        }
    }
