Inside Visual Studio LightSwitch

LightSwitch models are stored as part of the project in files having the .LSML extension. The Screen and EntityType building blocks encapsulate most of the client business logic. LightSwitch animates these building blocks at runtime with a screen object or an entity object. Creating a project in LightSwitch creates a model, which contains a description of the application in terms of building blocks.

• Debugging with IntelliTrace causes the application to run more slowly than debugging without it, and uses more memory as additional data needs to be recorded.
• Silverlight permissions are also elevated, giving LightSwitch desktop applications access to Windows and Office Automation and enabling the built-in Export-to-Excel functionality.
• Creating a project in LightSwitch creates a model, which contains a description of the application in terms of building blocks.
• The slogan for Visual Studio Community edition is “Free, fully-featured IDE for students, open-source and individual developers”.

These concepts are grounded in the LightSwitch building blocks. Some of the building blocks are concrete and have direct expression in the design environment such as a screen. Some of the building blocks are more abstract and used only under-the-hood.

The query is implemented in the service tier by its data service. Internally, the LightSwitch client is divided logically into the user interface, client business logic, and data service access. On September 16, 2011, a complete ‘Developer Preview’ of Visual Studio 11 was published on Microsoft’s website. Visual Studio 11 Developer Preview requires Windows 7, Windows Server 2008 R2, Windows 8, or later operating systems. “Visual Studio 2012 Update 1” (Visual Studio 2012.1) was released in November 2012.

Please help, this is very frustrating as I’ve expected so much from Microsoft but they failed to troubleshoot their faulty product. When you design a screen, you bind the screen’s data members to modeled queries. During PreprocessQuery, you can append additional query operators using LINQ.

LightSwitch is a rapid application deployment tool that provides a simplified development environment, enabling you to be more productive as a developer. Learn the basics of Visual Studio Lightswitch 2015 plus key advanced topics that every Microsoft developer needs to know to build robust, data-centric applications for the desktop, cloud, web and mobile devices. The set of building blocks in a model-centric architecture is often called a domain-specific language . In modeling parlance, each building block is a LightSwitch metatype, while the set of building blocks and their relationships is the LightSwitch metamodel.

In contrast, a source control plugin using the MSSCCI provides a set of functions that are used to implement various source control functionality, with a standard Visual Studio user interface. MSSCCI was first used to integrate Visual SourceSafe with Visual Studio 6.0 but was later opened up via the Visual Studio SDK. Visual Studio .NET 2002 used MSSCCI 1.1, and Visual Studio .NET 2003 used MSSCCI 1.2. Visual Studio 2005, 2008, and 2010 use MSSCCI Version 1.3, which adds support for rename and delete propagation, as well as asynchronous opening.

The threads can directly be named and flagged for easier identification from that window itself. In addition, in the code window, along with indicating the location of the currently executing instruction in the current thread, the currently executing instructions in other threads are also pointed out. As of 2010 a limited subset of the BCL source is available, with more library support planned for later.

Visual Studio 2008 is focused on development of Windows Vista, 2007 Office system, and Web applications. For visual design, a new Windows Presentation Foundation visual designer and a new HTML/CSS editor influenced by Microsoft Expression Web are included. Visual Studio 2008 also includes new code analysis tools, including the new Code Metrics tool . For Visual C++, Visual Studio adds a new version of Microsoft Foundation Classes (MFC 9.0) that adds support for the visual styles and UI controls introduced with Windows Vista. For native and managed code interoperability, Visual C++ introduces the STL/CLR, which is a port of the C++ Standard Template Library containers and algorithms to managed code. STL/CLR defines STL-like containers, iterators and algorithms that work on C++/CLI managed objects.

Visual Studio allows developers to write extensions for Visual Studio to extend its capabilities. These extensions “plug into” Visual Studio and extend its functionality. Macros represent repeatable tasks and actions that developers can record programmatically for saving, replaying, and distributing. Macros, however, cannot implement new commands or create tool windows. Add-Ins provide access to the Visual Studio object model and can interact with the IDE tools. Add-Ins can be used to implement new functionality and can add new tool windows.

Community developers as well as commercial developers can upload information about their extensions to Visual Studio .NET 2002 through Visual Studio 2010. Users of the site can rate and review the extensions to help assess the quality of extensions being posted. Internally a VSIX file is a ZIP file that contains some XML files, and possibly one or more DLL’s. One of the main advantages of these extensions is that they do not require Administrator rights to be installed.

Visual Studio Application Lifecycle Management

Visual C++ Toolkit 2003 is a version of the same C++ compiler shipped with Visual Studio .NET 2003 without the IDE that Microsoft made freely available. As of 2010 it is no longer available and the Express Editions have superseded it. Visual Studio .NET 2003 also supports Managed C++, which is the predecessor of C++/CLI. The internal version number of Visual Studio .NET 2003 is version 7.1 while the file format version is 8.0.

The basics are very easily understood but more advanced users will hunger for more. Visual Studio LightSwitch 2015 answers these questions and more as author Tim Leung―winner of a Microsoft 2011 Community Contributor Award for his LightSwitch expertise―covers this breakthrough product in detail. Visual Studio 2005 was upgraded to support all the new features introduced in .NET Framework 2.0, including generics and ASP.NET 2.0.

LightSwitch is included with Visual Studio 2012 Professional and higher. Visual Studio 2015 is the last release of Visual Studio that includes the LightSwitch tooling. In addition to the features provided by the Professional edition, the Enterprise edition provides a new set of software development, database development, collaboration, metrics, architecture, testing and reporting tools. After the release of Visual Studio 2008, Microsoft created the Visual Studio Gallery. It serves as the central location for posting information about extensions to Visual Studio.

A screen object represents a high-level unit of work in the client such as looking up a Customer or adding a new Order. Screens have logic for which data to load and save, and for validating their own private properties. Screens can have user-defined commands that drive the UI workflow.

They also have attributes that drive defaults for visualization and data entry. Entities are also between the client and the service tier, so you write business logic such as validation once and LightSwitch can execute it on both tiers. Let’s look more closely at each physical tier and drill into its logical composition. We’ll see how various building blocks and runtime objects are used to define and execute the application. LightSwitch includes graphical designers for designing entities and entity relationships, entity queries, and UI screens. Business logic may be written in either Visual Basic or Visual C#.

Building Blocks and DSLs

The Platform SDK included 64-bit compilers and 64-bit versions of the libraries.

The most basic edition of Visual Studio, the Community edition, is available free of charge. The slogan for Visual Studio Community edition is “Free, fully-featured IDE for students, open-source and individual developers”. Over 155 Xamarin UI controls to create cross-platform native mobile apps for iOS, Android, UWP and macOS platforms from a single C# code base. The service endpoint is implemented as a WCF RIA DomainService.

LightSwitch can connect to external data from SQL Server, SQL Azure, SharePoint, and other custom data sources. In the Execution phase, LightSwitch transforms the query expression into one that can be used directly by the given data provider. In some cases this involves transforming the data types used from LightSwitch-specific entity types to data types used by the underlying provider.
