Lightswitch Extensibility Toolkit for Visual Studio 2015 LightSwitch HTML Forums

Microsoft originally fielded LightSwitch (which was codenamed “KittyHawk”) back in 2010. Microsoft positioned LightSwitch, at that time, as a tool for non-professional coders to build business apps for the desktop, web, and cloud. Or can You suggest some other example showing how to deploy lightswitch with html-client to azure and enhance the Project with user-Management (e.g. users which can order and users which can maintain the product database. In this article we will create an end-to-end HTML application in Visual Studio LightSwitch. The purpose is to demonstrate how LightSwitch allows you to create professional business applications that would take a developer days to create.

LightSwitch then lets us plug our RIA Service into its infrastructure by again generating a WCF Data Service that exposes the custom-shaped data objects and operations of our RIA Service. For application-defined EntityTypes, LightSwitch has a special data source called “ApplicationData,” also referred to as the intrinsic database. In addition to creating the service-tier data service for the intrinsic database, LightSwitch also creates and publishes the SQL database.


(Previously, a more feature restricted Standard edition was available.) It provides an IDE for all supported development languages. MSDN support is available as MSDN https://cryptonews.wiki/ Essentials or the full MSDN library depending on licensing. It supports XML and XSLT editing, and can create deployment packages that only use ClickOnce and MSI.

A LightSwitch application follows the traditional 3-tier application architecture having a presentation tier, a service tier, and one or more data tiers. For example, a Customer, an Invoice, a Book or a TimeCardEntry. EntityTypes can have KeyProperties, Types of Cryptography Attacks EntityProperties, and NavigationProperties. A normal EntityProperty can store simple data values, or it can be a computed value that is not stored. NavigationProperties define links to related EntityTypes, for example, the Customer for an Order.

The API also includes classes that are generated from model elements. For example, a Customer class is generated from a Customer entity, enabling business logic to be written against the Customer class. The runtime raises numerous events where business logic can be written. One feature we are required to implement is to only show a user their own orders .

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 runtime also provides numerous extension points, enabling the addition of new controls, data types, visual themes, screen templates and more. What I am missing is a chapter explaining in deatil how to deploy this application to a new azure Website including SQL database and user access Management. I have followed it in your book rather than this blog and if functions as expected when run under Visual Studio.

Visual J++, InterDev, and the MSDN Library had all been using the same ‘environment’, called Developer Studio. Rapid Application Development environments have always been the subject of debate regarding the extent of their usefulness. Microsoft LightSwitch is no exception; many folks think of it as little more than an add-on tool primarily meant for mundane tasks like early application prototyping. If you’ve been ignoring or dismissing LightSwitch as a nice toy with limited use, I strongly suggest you take a deeper look.

During coding, the Visual Studio debugger lets certain functions be invoked manually from the Immediate tool window. The parameters to the method are supplied at the Immediate window. The server business logic consists of the query pipeline and the save pipeline. The logic defined for entities is also used for server-side data validation. LightSwitch ensures that the data is valid on the client before posting the changes to the data service. If all the modified entities are valid, it is sent to the service where it is validated again.

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. The Visual Studio debugger supports integrated debugging of the .NET 3.5 Framework Base Class Library which can dynamically download the BCL source code and debug symbols and allow stepping into the BCL source during debugging. As of 2010 a limited subset of the BCL source is available, with more library support planned for later. From client to server, the rapid application development promise is fulfilled, allowing us to build a complex business application in record time. 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.

It offers a way to build affordable, reliable, and scalable custom solutions with user-friendly views of your data. Visual Studio 2017 offers new features like support for EditorConfig , NGen support, .NET Core and Docker toolset , and Xamarin 4.3 . It also has a XAML Editor, improved IntelliSense, live unit testing, debugging enhancement and better IDE experience and productivity. Additionally, it is the last version of Visual Studio to support maintaining Windows 10 Mobile projects.

The developer uses LightSwitch to create a model containing screens, entities, queries and so forth that describe the application. In July 2011, Microsoft launched an initiative to help accelerate building Line-of-Business applications with Visual Studio LightSwitch – a stand-alone product that integrated with Visual Studio 2010. The promise of LightSwitch was to provide experienced developers, those with little experience, and non-developer business stakeholders with a faster way to build business applications. 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. As of Visual Studio 2010, the Professional edition is the entry level commercial edition of Visual Studio.

Unlike prior versions, Visual Studio 2012 cannot record and play macros and the macro editor has been removed. This was the first version of Visual Studio to require an NT-based Windows platform. Before that, Visual Basic, Visual C++, Visual FoxPro and Visual SourceSafe were sold as separate products. As of November 8, 2021, Visual Studio 2022 is a current production-ready version, and older versions such as 2013 and 2015 are on Extended Support, and 2017 and 2019 on Mainstream Support. Microsoft Visual Studio 2015 empowers you to write next-generation applications for any modern …

It encapsulates business rules about the data, such as data validation. 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.

When you design a screen, you bind the screen’s data members to modeled queries. At design-time, LightSwitch uses a local SQL Server Express database on the developer’s machine for the intrinsic database. In production, LightSwitch deploys the intrinsic database to Microsoft SQL Server Express, Microsoft SQL Server or Microsoft SQL Azure. If a save operation is successful, the client’s entities get updated with any changes that occurred to that data on the server, including updated key values for newly added entities. The client data service has a single SaveChanges method for sending a change set from the client data service to the corresponding server data service. The results of business rules are observable in the API via the Details property.
