问题
I was building/deploying my Windows Phone app in Visual Studio Professional 2013 with Update 3. The following console output showed up:
1>------ Build started: Project: CapturingVideos, Configuration: Debug ARM ------
2>------ Deploy started: Project: CapturingVideos, Configuration: Debug ARM ------
2>Deploying to Phone Internal Storage...

2>Warning : DEP0810 : This app references Microsoft.Phone.WinJS.2.1, version

Microsoft.Phone.WinJS.2.1 installed on the target machine, 1.0.9651.40228. If you
continue to run this application, it will run against the currently installed version,

the version of Microsoft.Phone.WinJS.2.1 that is installed.

I was curious about the Warning which suggested me to update the reference from WinJS.2.1 v1.0.9651.0 to v1.0.9651.40228. So I downloaded and installed the Visual Studio 2013 Extensions for the Windows Library for JavaScript. After restarting the OS and VS 2013, I tried to create a new Windows Phone project from the blank template. I expected the References folder to contain Windows Library for JavaScript 2.1 v1.0.9651.40228. However, it still only point to the old version, which was v1.0.9651.0. Was I on the wrong track or did I miss something? Please point me to the right direction. Thanks!

The issue is caused by wrong App Package Version number which is clearly displayed as 1.0.9651.0 in the reference properties despite all the .js and .css files the package contains have the correct build number 1.0.9651.40228 specified in their headers.
The App Package Version property takes its value from package's manifest file %Program Files%\Microsoft SDKs\WindowsPhoneApp\v8.1\ExtensionSDKs\Microsoft.Phone.WinJS.2.1\1.0\SDKManifest.xml particularly from the following line:
FrameworkIdentity="Name=Microsoft.Phone.WinJS.2.1, MinVersion=1.0.9651.0"
So tick the file's Read-only flag off, open it as an administrator and change the MinVersion number. Reload your solution. The warning message should disappear.

I had the same issue and found this blog post, along with your question here on StackOverflow:
http://blogs.msdn.com/b/lighthouse/archive/2014/04/21/can-t-update-visual-studio-2013-extensions-for-the-windows-library-for-javascript.aspx
I didn't have the issues your describing, or the issues warned about in the blog post, but they explained how to correct them with a powershell script.
