Hi, There is a xamarin project I participated in these days. I can build the project debug mode and apk runnig properly. everthin is ok in APK. But When I want to distrubute the apk with release mode then The Project builded succeeded but APK doesn't work and throwig an error which "Method not found: void CloseConnectionGroups(string) at System.Net.Http.HttpMessagehandler.Dispose () [0x00000] in <>"![78539-xam1.png][1] [1]: /answers/storage/attachments/78539-xam1.png Actually, I can see the method in System.Net dll But Xamarin couldn't process the method properly and move the apk.
