From client to server, the rapid application development promise is fulfilled, allowing us to build a complex business application in record time. If you’ve been tempted to write off LightSwitch as a mere gadget, a Silverlight-dependent casualty of browser evolution, or just a thing of the past, think again. The platform, more than ever, stands firmly as the fastest way to build an n-tier line-of-business application using the MS stack.

LightSwitch generates the SQL database schema for the intrinsic database from its modeled EntityContainer and deploys the database schema when you publish the application. It will also attempt to update an existing database schema whenever you deploy an update to the application. 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.

It provides the common elements for logging in, launching and activating screens. A LightSwitch browser application can be hosted within any browser and on any OS that Silverlight 4.0 supports. In that case access to OLE Automation is not available (thus Export-to-Excel is not available) and access to the Windows file system is restricted.

Inside Visual Studio LightSwitch

Release v1.0 corresponds to the code in the published book, without corrections or updates. Ok, so we have a site where most of the users have local admin and they have a small group of users who “know about computers”. The site runs pretty smoothly but we’re seeing a bunch of users who are able to function on the wired network but aren’t able … Probably you are using anonymizers/proxy/VPN or similar tools (TOR, friGate, ZenMate etc.).

In particular, he possesses deep knowledge of the Microsoft .NET Framework and SQL Server. Developer community and often delivers presentations on technical topics. He is passionate about the concept of rapid application development and was awarded the Microsoft Community Contributor Award in 2011 for contributions to the LightSwitch community. Keep your technology and business options open, while building a practical yet scalable application that matches your current needs now and in the future.

This worsened the uncertainty caused by the end-of-support announcement for Silverlight in 2021. Microsoft also announced Visual Studio Tools for Applications as the successor to Visual Basic for Applications and VSA . It is included with What Is a Program Manager vs a Project Manager Office 2007 and is also part of the Visual Studio 2005 SDK. VSTA consists of a customized IDE, based on the Visual Studio 2005 IDE, and a runtime that can be embedded in applications to expose its features via the .NET object model.

Introducing LightSwitch

Notably the tool was purchased and installed as a stand-alone product. If Visual Studio 2010 Professional or higher was already installed on the machine, LightSwitch would integrate into that. The second major difference was the middle tier was built and exposed using WCF RIA Services. During Visual Studio 11 beta, Microsoft eliminated the use of color within tools except in cases where color is used for notification or status change purposes. However, the use of color was returned after feedback demanding more contrast, differentiation, clarity and “energy” in the user interface.

• 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.
• After the release of Visual Studio 2008, Microsoft created the Visual Studio Gallery.
• Visual Studio 2015 is the last release of Visual Studio that includes the LightSwitch tooling.
• It is aimed for development of custom development environments, either for a specific language or a specific scenario.

Visual Studio 2008 introduced the Visual Studio Shell that allows for development of a customized version of the IDE. The Visual Studio Shell defines Robotic Process Automation RPA for Financial Services a set of VSPackages that provide the functionality required in any IDE. On top of that, other packages can be added to customize the installation.

For example, if you add a “Northwind” SQL data source and a “MySharePoint” data source, you’ll see one client data service member for each in the data workspace. An entity object represents a copy of a durable piece of business data. 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.

The shape of the service interface corresponds logically to the EntityContainer definition described above. The Control building block provides visualization or editing of a particular data type, or provides visual layout. LightSwitch has many built-in controls and new controls can be added as an extension point. LightSwitch also employs a theming service that controls basic visual attributes Create a Portfolio Website on WordPress Premade Templates such as control colors, fonts, and to support the OS high-contrast themes. 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. Let’s look more closely at each physical tier and drill into its logical composition.

Add-in Types

On March 14, 2017, first fix was released for Visual Studio 2017 due to failures during installation or opening solutions in the first release. Initially referred to as Visual Studio “15”, it was released on March 7, 2017. Unlike prior versions, Visual Studio 2012 cannot record and play macros and the macro editor has been removed.

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. This update added support for Windows XP targets and also added other new tools and features (e.g. improved diagnostics and testing support for Windows Store apps).

NavigationProperties define links to related EntityTypes, for example, the Customer for an Order. A model-centric architecture uses models to describe the structure and semantics of an end-to-end application. The applications that you build with LightSwitch have a traditional N-tier architecture. Microsoft Visual Studio LightSwitch uses a model-centric architecture for defining, building, and executing a 3-tier LightSwitch application.

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. Going one step further, we may question the usefulness of our server application in scenarios involving non-OData clients. Another powerful extensibility point in LightSwitch allows us to access our server application object model from any non-LightSwitch code running in the same ASP.NET application (e.g. a web form or Web API controller).

Visual Studio

Support for programming languages is added by using a specific VSPackage called a Language Service. A language service defines various interfaces which the VSPackage implementation can implement to add support for various functionalities. Functionalities that can be added this way include syntax coloring, statement completion, brace matching, parameter information tooltips, member lists, and error markers for background compilation.

Refining Your Application

With Microsoft Visual Studio LightSwitch 2011, building business applications has never been easier. Microsoft Visual Studio LightSwitch gives you a simpler and faster way to create high-quality business applications for the desktop and the cloud.

Each screen in the client has a data workspace that provides access to all of the data services in the application. The service operations will enforce the entity relationships and business rules we defined on every invocation. Of course, we can also add security rules and decide who can access service operations. Additionally, the LightSwitch team has put a strong focus on the HTML client since 2012. The client is very cleverly integrated into the same RAD designer experience used for the Silverlight client.

It lets us create responsive mobile HTML5 clients in a flash and fully customize them by writing or plugging in code. We build our server logic — data entities, data access layer, queries, business rules – with incredible ease, before it’s automatically exposed as service operations for client consumption.
