از برنامه‌های وب ASP.NET Core گرفته تا برنامه‌های Xamarin، برنامه‌های ویندوزی و کنسول، اغلب با یک API یکپارچه می‌شوند. برای این کار، HttpClient گزینه‌ی پیش فرض و بهترین گزینه است. اما استفاده از آن خیلی بیشتر از ارسال درخواست و خواندن پاسخ است. در دوره ویدیویی Using HttpClient to Consume APIs in .NET Core (استفاده از HttpClient برای استفاده از APIها در دات نت کور) موسسه Pluralsight که توسط Kevin Dockx تدریس شده است، نگاهی دقیق به استفاده از HttpClient و HttpClientFactory خواهید انداخت و از ساز و کار داخلی و تعاملات CRUD پایه تا کار با streamها و فشرده سازی را بررسی خواهید کرد. ما همچنین لغو درخواست هایی را که دیگر نیازی به آنها نیست را پوشش خواهیم داد. علاوه بر این، شما یاد خواهید گرفت که چگونه از handlerهای پیام سفارشی برای بهبود قابلیت اطمینان درخواست‌های خود و آزمون واحد استفاده کنید. پس از به پایان رساندن این دوره، شما با زیر و بم یکپارچه کردن با APIهای انواع مختلف برنامه ها، آشنا خواهید شد.
