Second, if I update the version number in the app manifest and upload the app in developer console, the version number is always 1.0.0.0. It's a bug or is normal?

问题 I have a Cordova plugin which works fine for both Android & iOS. However, it fails when ported to Windows Phone 8 because it seems that multiple outstanding callbacks are not supported in Cordova for Windows Phone. The problem is this: When a DispatchCommandResult is called with a PluginResult which has KeepCallback set to true, a further DispatchCommand from a different method will call both its callback and the previous callback (the one with KeepCallback set to true).

问题 I've installed Windows Phone SDK 8.0 and there are no project types for desktop windows RT applications. How can I develop this type of applications? 回答1: Windows Phone 8 and Windows 8 are two separate products and require 2 separate SDKs to develop for.

All you need to do to build Windows 8 apps is a machine with Windows 8 and Visual Studio 2012 installed on it. You can use the 90 day

问题 So I ran across some bizarre behavior. I am an the first page with a ViewModel. The ViewModel only contains a ObservableCollection. When I navigate on the second page everything seems fine.

问题 I have already download the windows phone develop tools but I don't know how to using F# to developing the app, currently it's C#. 回答1: Installing a template for 'F# and Windows Phone' into Visual Studio makes life a little easier.

From there, if you select the online gallery and type 'F# Windows Phone' into the search box you can find a couple of templates that should help you get started.

问题 Does anyone know of any good tools to detect memory leaks on the Windows phone 7.5 platform? 回答1: The built-in profiling tools are probably the best starting point. Select: Debug > Start Windows Phone Perfomance Analysis and select the the "Memory" option This will help you see any memory spikes and leaks and help you drill down to the cause.
