XAML Apps fail with 'SetSwapChain failed' on 8.1/VS2013

Creating a simple project (three spinning cubes) and exporting it as either a C# or C++ XAML app compiles fine in VS2013 (after fixing broken references) but after displaying the Unity logo the app hangs indefinitely on a black screen.

The only data that makes it into the log file is:

Code (csharp):

1. Module information:

D3D11 C# apps run fine after you fix the missing reference, I haven't tried it with D3D11 C++ but I assume it works.

I need a XAML project so I can implement the settings charm and making the app native to 8.1 is a requirement of our publisher.

Project is attached. The build folder marked with _C is the C++ version and the one without is the C# version.

Any help much appreciated!

 

I'm not finding any of the visual studio related project files in your zip... it only contains the basic Unity project package.

You will need to provide your app.xaml.cs and/or the mainpage.xaml.cs for us to see what could be causing the error...

 

Yes I did retarget the app, our publisher requires us to target 8.1 natively. I also need implement the settings charm and apparently the API is different between versions?

Here is the C# XAML project (minus the players folder). I couldn't get the C++ version under the upload limit, all I did for it was re-target the app after it built, it didn't need any references changed.
