Download Visual Studio Lightswitch 2015, 2nd Edition free PDF by Tim Leung

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 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.

LightSwitch Code Samples

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.

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 As of 2010 it is no longer available and the Express Editions have superseded it.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 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.

Lightswitch Extensibility Toolkit for Visual Studio 2015

Development for Windows Mobile is no longer supported in Visual Studio 2010. The Visual Studio Debugger allows setting breakpoints and watches . Breakpoints can be conditional, meaning they get triggered when the condition is met. It can either step into functions to debug inside it, or step over it, i.e., the execution of the function body isn’t available for manual inspection. The debugger supports Edit and Continue, i.e., it allows code to be edited as it is being debugged. When debugging, if the mouse pointer hovers over any variable, its current value is displayed in a tooltip (“data tooltips”), where it can also be modified if desired.

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.

If all the modified entities are valid, it is sent to the service where it is validated again. If any have validation errors, LightSwitch disables the screen’s Save command to prevent the end-user from attempting to save bad data. Some business rules are declarative and are specified in the designer. The built-in validation rules include Required and Range among others. The LightSwitch user interface consists of the shell and screens, and controls. On November 14, 2016, for a brief period of time, Microsoft released a blog post revealing Visual Studio 2017 product name version alongside upcoming features.

When a query operation is invoked at runtime, execution passes through the query pipeline. Read-only rules determine whether an entity or screen property is currently read-only. Computed properties return a dynamically evaluated value for an entity property.

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.

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.

QueryOperations return a selection of entities from an EntitySet or from another QueryOperation. Building blocks have relationships to each other as well, with, for example, screens binding to queries that return entities. As of October 14, 2016, Microsoft no longer recommends LightSwitch for new application development. The preview for Visual Studio 2013 was announced at the Build 2013 conference and made available on June 26, 2013.

Functional Programming in C#: How to write better C# code

Each data service is logically made up of a service interface, the server business logic and the back-end data access providers. Each client data service exposes access to the entity sets and query operations available in the data service. You can write LINQ queries against these to fetch remote data locally.

Some speculated that the root cause of the redesign was to incorporate the simplistic look and feel of Metro programs. However, there exists a Windows Registry option to allow users to disable the all-caps interface. In April 2003, Microsoft introduced a minor upgrade to Visual Studio .NET called Visual Studio .NET 2003, codenamed Everett . It includes an upgrade to the .NET Framework, version 1.1, and is the first release to support developing programs for mobile devices, using ASP.NET or the .NET Compact Framework. The Visual C++ compiler’s standards-compliance improved, especially in the area of partial template specialization.

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.

  • Visual Studio 2015 is the last release of Visual Studio that includes the LightSwitch tooling.
  • Intrinsic Silverlight controls support styling, but LightSwitch goes one further by defining a set of styles as a theme and ensuring that the controls used for the shell and screens will select styles from the current theme.
  • Add-Ins can be used to implement new functionality and can add new tool windows.
  • As of October 14, 2016, Microsoft no longer recommends LightSwitch for new application development.

Add-Ins are plugged into the IDE via COM and can be created in any COM-compliant languages. Packages are created using the Visual Studio SDK and provide the highest level of extensibility. They can create designers and other tools, as well as integrate other programming languages. The Visual Studio SDK provides unmanaged APIs as well as a managed API to accomplish these tasks.

The client data model centers on entities that are accessed from a data service on the service tier. The client’s local copy of entities are managed in a client data service. Each screen in the client has a data workspace that provides access to all of the data services in the application. Visual Studio Application Lifecycle Management is a collection of integrated software development tools developed by Microsoft.

The Data Tier

Visual Studio 2010 no longer supports development for Windows Mobile prior to Windows Phone 7. On April 12, 2010, Microsoft released Visual Studio 2010, codenamed Dev10, and .NET Framework 4. It is the last version to support Windows XP SP3, Windows Server 2003 SP2, Windows Vista SP1, Windows How to Get Into Cybersecurity With No Experience Server 2008 below SP2, Windows 7 before SP1 and Windows Server 2008 R2 before SP1. Visual Studio 97 was an attempt at using the same development environment for multiple languages. Visual J++, InterDev, and the MSDN Library had all been using the same ‘environment’, called Developer Studio.

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 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.

Building Blocks and DSLs

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.
