Hello,
I was trying to run the Xamarin Store app - shown at the Build 2014. After downloading the project and the android , ios and xamarin studio stuff , I couldnt get it run on VS 2012 Ultimate....the app would say - "Built with evaluation software. This build will work only for 24 hours".
I guess, this sort of message - comes because of me using a trial version of Xamarin, but I just followed instructions given here https://xamarin.com/sharp-shirt
Thanks - Anand
