LibSpotify and Windows Store App - windows-runtime

I'd like to start work on a Windows Store App client for Spotify, using LibSpotify. However, it seems that I'm unable to use the libspotify dll from inside a Metro app, presumably because it uses parts of the win32 api that are off-limits to the Metro Sandbox.
Loading in my own simple test dll using LoadPackagedLibrary works ok, but loading in libspotify gives error 1114 - ERROR_DLL_INIT_FAILED.
Is there any hope for me?
Thanks
Tom

If you are trying to create a Metro-Style-App - you have no hope until Spotify releases an updated library or someone reverse engineers their library to make it work in WinRT.
If you want to create a Metro style app that is not WinRT - based - there are WPF libraries that let you theme your application to look Metro, but you won't be able to sell it in Windows Store unless you work for Spotify and get into a deal with Microsoft.

You can only use the WinRT library in Windows 8 Metro Apps, not Win32.

Xamarin WP8 DataTransferManager

Windows Phone API has the namespace DataTransferManager to share files from internal storage.
I'm trying to use this feature on my Xamarin App.
I got a WP8 XAML page displayed via Xamarin's PageRenderer. Inside this page I call DataTransferManager.GetForCurrentView() like described in many tutorials. But at runtime the App crashes with NotSupportedException.
Please help me on how I can share files (no pictures) from my App.
Thanks
I found a solution: Upgrading the WinPhone Project to WP8.1.
So far there are no errors with PCL and 8.1.

Windows Store WinJS App and LESS

Is it possible to use LESS files in a WinJS application for the Windows Store?
I like how the Web Essentials extension works with web apps and would like to have this functionality in my WinJS app.
Yes, as long as you've got it setup to compile and you add the output CSS files to your project, it works fine. I'm using it in a WinJS project.

Connecting Salesforce with Adobe AIR

I am trying to Connecting Salesforce with Adobe Air Application i.e. pulling data from Sales force to the AIR application. I tried this with Developerforce toolkit. But its not working. I tried the example from this following reference http://wiki.developerforce.com/page/Taking_Data_Offline_Using_Adobe_AIR . Please help me in this. And also please tell me is there any way to connect salesforce with AIR application.
Note: Im using Flashbuilder as IDE.
Thanks in Advance.
The best way to do this is to use the OAuth code from the provided toolkit and then to use the Rest API with the various AIR HTTP classes to do the rest yourself, there's libraries available for parsing the JSON to local actionscript objects.

Can we use Microsoft.Phone.DeviceManufacturers namespace in official Windows Phone 8 sdk?

Who knows if we can reference Microsoft.Phone.DeviceManufacturers component within official windows phone 8 sdk? I want to develop a background service using ServiceAgent class.
From MSDN (http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj208461(v=vs.105).aspx)
"This API is not intended to be used directly from your code."
So, no you can't use this for a normal SDK app which you distribute via the Store - this is a restricted API. You may be able to use this in an app which you load on a dev-unlocked phone.
