If required, restart Visual Studio 2015 after installing the extension. By doing so, a UWP app that uses SQLite will also include the precompiled database engine binaries. In this case, download and install the SQLite for Universal Windows Platform extension. There are several SQLite extensions, each targeting a specific Windows version, that can be downloaded using the Extensions and Updates tool in Visual Studio 2015, as shown in Figure 1.įigure 1 Downloading the SQLite for Universal Windows Platform Extension in Visual Studio 2015 I describe this before showing how to create new projects because the extension works at the IDE level, not at the project level, and will supply the precompiled SQLite binaries every time you include the SQLite libraries in your solutions. Instead of manually including such binaries with every project, you can take advantage of the SQLite extension for Visual Studio 2015, which provides precompiled binaries for the database engine and automates the task of including the required files with new projects. Therefore, you need to include SQLite binaries with your app package. The SQLite core engine is already included on iOS and Android, but not on Windows. Both this article and the sample code are based on Xamarin.Forms 2.0, which you get by installing Xamarin 4.0.3. The latter describes how to work with data over the Microsoft Azure platform. For further information, you can read the following articles: “Build a Cross-Platform UX with Xamarin.Forms” ( /magazine/mt595754), “Share UI Code Across Mobile Platforms with Xamarin.Forms” ( /magazine/dn904669) and “Build a Cross-Platform, Mobile Golf App Using C# and Xamarin” ( /magazine/dn630648). I assume you already know how to create a Xamarin.Forms application with Visual Studio 2015 what XAML is and how to debug a Xamarin.Forms app using the different emulators included with the various platform SDKs. In this article, I’ll show how to create a mobile app that targets Android, iOS, and the Universal Windows Platform (UWP) with Xamarin.Forms, and that takes advantage of SQLite to store and retrieve local data. For this reason, SQLite also is the perfect companion to build cross-platform, data-centric mobile apps with Xamarin.Forms that need a local database. In fact, it’s pre-installed on both iOS and Android, and it can be easily deployed to Windows, as well. SQLite perfectly suits cross-platform development, because it’s a portable database engine. Information is stored inside tables and data operations can be performed writing C# code and LINQ queries. SQLite is an open source, lightweight, serverless database engine that makes it simple to create local databases and perform operations on data. The good news is that you can easily include local databases in your mobile app using SQLite ( ). In the case of complex, structured data, applications need a different way to store information. With simple, unstructured data, such as user settings and options, applications can store information inside local files, such as XML or text, or through specific objects offered by the various development platforms. However, there are situations in which mobile apps only need to store data locally. In many cases, mobile apps exchange data over networks and take advantage of cloud storage and services such as push notifications. This is true not only for desktop and Web applications, but also for mobile apps. More often than not, applications work with data.
