Where to find Phone.dll file for getting Call Logs (PhoneOpenCallLog)?

I can't find Phone.dll file on my computer and getting Can't find PInvoke DLL 'Phone.dll开发者_如何学JAVA'.

Where will I find Phone.dll file?

It's not a DLL that you "find". It is shipped on the device, baked into the ROM. It would be in the |Windows folder, and most likely a hidden file, meaning that you probably can't see it using the on-device explorer, though the Remote File Viewer will show it.

If a p/invoke call is not finding it, however, it's likely that it's not there. What type of device, specifically, are you targeting? Obviously not all WinMo devices are phone devices, so if it's not a phone device the DLL won't be present. I don't believe it's present in the emulator either.
