The new release of Windows Phone and Windows 8.1 dramatically expands the ways in which developers can build applications and games, by adding several new programming models, and also expanding the application model to support a broader set of developer scenarios. We explore these in depth and give you the information you need to get started building applications that leverage these features today.
Come hear the master of Windows troubleshooting, walk you step-by-step through how he has solved seemingly unsolvable system and application problems on Windows. With all-new real case studies, I will show you how to apply the Microsoft Debugging Tools and his own Sysinternals tools, including Process Explorer, Process Monitor, to solve system crashes, process hangs, security vulnerabilities, DLL conflicts, permissions problems, registry misconfiguration, network hangs, and file system issues. These tools are used on a daily basis by Microsoft Product Support and have been used effectively to solve a wide variety of desktop and server issues, so being familiar with their operation and application will assist you in dealing with different problems on Windows.
DAX is not only an expression language, but also a query language and, when it comes to performance, the xVelocity in-memory engine is second to none. Scanning fact tables and performing leaf-level computation happens in a matter of milliseconds. Nevertheless, as with any other language, you can write good DAX or bad DAX, depending on your understanding of the engine internals. This session introduces DAX as a query language, showing the different ways of querying with DAX using real-world data. Some queries will be fast, others will need optimizations. Many practical examples based on common patterns and an analysis of the query plans will show how to get the best out of DAX.
Most mobile apps require the ability to store data locally on a device to deal with the realities of a disconnected world where a ubiquitous wireless data network is non-existent. While many consumer apps can save light amounts of data as small files, the data requirements of mobile line-of-business apps is much greater. With Windows Phone 8.1 and Windows 8.1, and using MSOpenTech’s new portable wrapper for the embedded database, SQLite, C# and Visual Basic developers can build structured data storage into their apps. Join Rob as he walks you through creating local databases and tables and shows you how to work with offline data. We also take a quick look at the new local data sync capability in Microsoft Azure Mobile Services which uses SQLite for local data storage.
