में लटकता है मैं निम्नानुसार कैश प्रविष्टियों को साफ़ करने के लिए पी # के साथ पी/Invoke का उपयोग कर रहा हूं। कोड 32 और 64 बिट पर विंडोज 7 तक ठीक काम करता प्रतीत होता है। विंडोज 8 रिलीज उम्मीदवार पर, यह DeleteUrlsFromGroup कॉल पर लटकता है।विनीनेट कैश एपीआई विंडोज 8

विंडोज 8 के लिए विन एपीआई में बदलावों के लिए कोई अंतर्दृष्टि/संदर्भ?
