for the enterprise

4. Motivation for LightSwitch
• LightSwitch is a development tool that
Is designed to be used by business users
In the same way they are using Excel and Access today
Is designed to be used by developers
Apps can be transitioned to devs if they grow beyond the workgroup
Has built-in “plumbing” to handle common application requirements
Uses the latest Microsoft technologies
HTML5, JavaScript, Silverlight, Entity Framework, WCF, SQL Server
Uses well-known architectural patters

5. LightSwitch Simplifies Development
• Data
Multiple sources / kinds (including SharePoint)
Entity model
• Screens
No markup solution
Extensible controls
Extensible layouts
• Rules and validation
Write once, execute everywhere
11. Entities
• Can be local (SQL Server Express) or attached (SQL
Server, SQL Azure, SharePoint, WCF RIA service)
• Can create relationships within and across data sources
• Custom business types
Provide validation and formatting
• Calculated properties
Write code to generate value
• Can validate at the entity or property level
12. Screens
• Variety of built in screens
New, search, details, editable grid, list and details
• Can use auto-generated screens for adding/editing or
create your own
• Developers can modify screens at design-time and runtime
• Always based on queries
• Generated screens do not expose XAML
You can use Silverlight controls you create yourself
You can add UI elements packaged as extensions
13. Queries
• LightSwitch creates queries automatically
Select * query is a collection, eg. CustomerCollection
Select where query is a detail, eg. CustomerDetail
• You can edit existing queries
Filter, sort, add parameters
• You can create new queries
• You can base queries on other queries
16. Access Control
• Authentication
LightSwitch supports Windows and Forms authentication
• Authorization
Check if the user is allowed to do something
Define permissions and check them in code at entity
and property level
Permissions are granted through administration screens
17. Access Control
• Permissions are defined by the developer
• The application’s administrator(s) define(s) users and roles
• Permissions are assigned to roles
• Users are assigned to roles
• A user’s effective permissions are the combined
permissions assigned to their roles
