Q - I have WP8 SDK and I installed the NuGet package, it is still installing the 7.1 version of the toolkit assembly, or I get an error – “You are trying to install this package into a project that targets 'WindowsPhone,Version=v8.0', but the package does not contain any assembly references that are compatible with that framework.”

A – You have an older version of NuGet. 
Install the latest NuGet from www.NuGet.org . Close and restart all the 
instances of Visual Studio. 
Now install the package. It will install correctly. 
WP8 projects are supported from Nuget 2.1 onwards.

After that go to xaml page type
