We are now going to expand on what we did in Chapter 6, An Architectural Taste, and provide a mobile app to perform the same things. Unfortunately, Bifrost Client doesn't have all the facilities in place for the CQRS and DDD stack yet but we will manage. This is something that will get a lot more attention and you will love moving forward.
Before you start, make sure that you have installed the Windows Phone 8.1 extensions to Visual Studio, and make sure you have everything up to date. If you haven't installed the prerequisites, refer to http://dev.windows.com/en-us/develop/download-phone-sdk. To install the Windows Phone 8.1 extensions, follow these steps:
Open Visual Studio and create a new project by clicking on New from the FILE menu.
From the left-hand side menu, open Store Apps and select Windows Phone Apps. For simplicity, we will only build a phone version, but you can also use the universal and targeted version rather than just the phone version...
