Windows Azure Mobile Services in Windows 8.1 apps (Unity 4.3), is it possible?

Hi,
I have been trying to use Windows Azure Mobile Services in Windows 8.1 apps without success, is it possible?

I do this by using a custom made plugin (following the plugin guide for Windows provided by Unity) that adds the Windows Azure Mobile Services libraries by using NuGet.

It used to work without issues when exporting from Unity to Windows 8.0.

But when I updated the project from Windows 8.0 to Windows 8.1 it doesn’t work. I have tried creating a new Unity project with a new plugin project targetting the .Net Framework 4.5.1, adding the Windows Azure Mobile Services NuGet package, and added a simple function that just reads from the service but it doesn’t work.

The error I get is when I try to build the exported solution from Visual Studio 2013:
System.Net.Http.Extensions.dll failed. System.IO.FileLoadException: Could not load file or assembly 'System.Core, Version=4.0.0.0…

It seems that the System.Net.Http.Extensions.dll is the wrong version or something, but I do copy the DLL from the Bin folder of the plugin for Windows Store.

Anyone here who has successfully used Windows Azure Mobile Services in Windows 8.1 Store Apps? Is it possible?

The plugin works if I create a new normal Windows Store app using the Visual Studio Templates, so it seems to be something with the project Unity exports.

Any help would be very appreciated, as I have had this problem for many weeks now and project is on hold.

Is there anyone here who has successfully managed to use Windows Azure Mobile Services in a Windows 8.1 untiy game?

It’s something not clear here. You’re saying you get “System.Net.Http.Extensions.dll failed. System.IO.FileLoadException: Could not load file or assembly 'System.Core, Version=4.0.0.0…” , is this error thrown by Visual Studio. If so, then that means there’s some inconsistency here. If you only get this with Unity’s exported project.

Be really really sure that you’re using same System.Net.Http.Extensions.dll in both solution - made by Unity from VS templates. Because I think you have incorrect dll somewhere.

Thanks for the response!
Yes, it is Visual Studio that throws this exception.
What is the correct way of adding the Windows Azure Mobile Services SDK to a plugin solution? Right now I just add it using the NuGet Manager in the Plugin project.

I also copy all of the DLLs that the compiler creates when building the Plugin project, to the Metro-folder in the Assets/Plugin folder (this includes many DLLs that the Mobiler Services is dependent upon that the NuGet package installs).

With NuGet, I am not really sure, but apparently you don’t copy something. Please compare the solution created by Unity and the one from VS templates, and see if you can spot differences.
