Hi nitm,
The first thing you are seeing about XP is a known issue that we've fixed in the development branch and it will be in our next release 2.3.0. Basically we had a problem that was causing the XP targeting project file to not be correctly loaded into the solution. That is why when you see the BingRequest sample failing to build due to not being able to find the XP lib. If you want to continue to work out of the master branch you can just unload the BingRequest XP sample from the solution in Visual Studio and continue.
For the second issue I'm guessing you are using a version of Visual Studio express that doesn't support building for Windows Store and Phone, the 'Winrt' solution file. To build for Windows desktop you need to use Express 2013 for Windows Desktop. To build for the Windows Store and Phone you need Express 2013 for Windows.
