Simple question – complex answer! Over the years, Microsoft has offered a number of data access technologies such as MDAC, ADO.NET, Entity Framework and SQLClient, and client-side databases such as SQL Server CE and Jet. But in the brave new world of UWP, at first glance, Microsoft appears to be offering – nothing!Not so. In UWP, we have Windows.Storage APIs for efficient async file storage, and XML and JSON serializers for converting in-memory data objects to and from tokenized strings for file storage or network transfer. Entity Framework 7 allows you to define your data objects “code-first” and then use a provider to store in a backing store that in a UWP app can be in-memory or SQLite. Speaking of SQLite – yes, we have great support for that as well, through a variety of different wrappers that allow you to program against it using SQL statements, or through lightweight ORMs. And for creating a cloud backend for your mobile app, including support for offline and datasync, we have the excellent Azure App Service Mobile App SDKs. In this talk, we’ll look at the pros and cons of each technique, and leave you with a clear idea of how to handle data in your UWP app.
