wcf - Is portable class libraries are beneficial for window 8 store apps -

-

is portable class libraries beneficial window 8 store apps. trying create architecture window 8 app in have wcf restful service data. problem don't want create proxy classes each entity in window 8 project, want use datalayer in have entities , business logic's, data layer has reference in wcf service return me xml/json result. need consume service in window 8 app need map data proxy classes don't want create.

so problem can refer datalayer window 8 app project, @ time found impossible window 8 app project doesn't support system.data. or, can 1 tell me pattern should use achieve goal.

does portable class libraries me out of ?

portable class libraries used solve problem of sharing backend code (business logic/data layer) between multiple frontend client apps (windows 7, windows 8, silverlight, windows phone, , xbox 360). if writing both windows 8 app , else (say windows phone app), put backend logic in portable class library, , build assembly reference both windows 8 app , windows phone app.

so, portable class libraries not tool need solve problem, needing consume service in window 8 app. if bing search "consume json in windows 8", there lot of results can this.

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
