بعد از خوندن مطلب ، اول فکر کردم که استفاده از jQuery UI ضروری نیست و فقط در صورتی که بخوایم امکان autoComplete رو فعال کنیم باید رفرنسی به اون بدیم اما بعد از حذف کردن متوجه شدم که اینطور نیست و کلا این plugin هم به jQuery و هم به jQuery UI وابسته است و بدون UI کار نمی‌کنه .

What’s in this build? Significant performance improvements were made, shared projects are now supported, code inspection severity can be configured, settings for our unit test runner can be edited, various updates to the NuGet tool window UI, and more. Check out the list of fixes in this build if you feel like digging into details.
