Visual Studio LightSwitch
What is Visual LightSwitch?
Microsoft Visual Studio LightSwitch
is a development environment designed to simplify and shorten the development
of typical forms-over-data applications for businesses. Regardless of your
development skills—whether you’re a beginner or an experienced developer—LightSwitch enables you to quickly
create professional-quality business applications. And you can do so without
writing a line of code.
In most business applications, developers spend a large
amount of time:
Writing code to interact with a data source
Creating a user interface
Writing code to specify the business logic
With LightSwitch, your application can point to an existing
data source—or databases that are automatically created—without the need to
write code. For the user interface, LightSwitch provides screens that are based
on predefined templates. They allow you to display data automatically by simply
specifying which elements you want to show.
For the business logic, LightSwitch allows you to do simple
validation such as required fields and minimum numeric values. But LightSwitch
also gives developers the ability to write more complex business logic code for
such scenarios as saving changes to a data source or performing authorization
LightSwitch in Depth:
LightSwitch applications are built on classic three-tier architecture (UI, BAL, DAL), on top of existing
.NET technologies. The LightSwitch presentation tier (User Interface tier) is a
Silverlight application. It can run as a Windows desktop application or hosted
in a browser. The LightSwitch logic (Business logic layer) tier exposes a set
of WCF RIA DomainServices running in ASP.NET. The logic tier process can be
hosted locally (on the user’s machine), on an IIS server, or in Windows Azure.
A LightSwitch application’s primary application storage uses
SQL Server or SQL Azure and can consume data from existing SharePoint 2010
lists, databases accessible via an Entity Framework provider, and custom build
WCF RIA DomainServices.
