How we created offline maps for Windows Phone
2GIS is a city guide with maps. We already have a Windows Phone version but it depends on the Internet connection, and a key feature of our application has always been an ability to work offline. I will tell you how we created and offline version of 2GIS for Windows Phone. We will talk about the cross-platform core on С++ and platform-specific components on С#. We will also tell why we selected Caliburn.Micro as an MVVM framework. I will share my experience on how to make a map on OpenGL and offer PixelPerfect support to designers.
