Existing application written in C# and running on Windows, Mac (Xamarin) and iPad (Xamarin) stores data in a simple binary serialised format. This information needs to be synchronised between the different platforms. For example, a user might have two Windows installations running, or might have Windows and iPad. The data file must be synchronised on change between each of these instances using a cloud server. I require a simple "last writer wins" synchronisation routine developing for both the client and server side. The client side will need to be written using portable C# and will communicate with the server through a simple API. The server side will be written in C# and deployed as part of an existing website project using the Azure platform. Data storage on the server side will be in Azure blob storage. The developer will develop a working synchronisation solution which will be demonstrated using multiple copies of the windows software and cloud server provided by the developer hosting the server process. Deliverables will be a synchronisation library for the client software and a server library. Immediate start required.
