Problems:
Nowhere to keep local data
Keeping local and server in sync
What it is:
• Very small (~1MB) embedded, in-proc database
• Nice subset of SQL Server types and SQL dialect
• Does not have: Stored Procs, Views, Xquery
• Why limit programming to T-SQL when you have managed code
Where it’s
deployed
• Mobile & Embedded devices
• Windows Vista, Media Center PC, MSN Client,
ZUNE, Windows Media Player, …
• Default Local/Client database offering in VS 2008
Scenarios
•
•
•
•
Local online / offline cache
Local, stand alone application database
Persistent data manager for In-Memory database
Structured document format for custom apps
Allows us to sync data from client to
server
But is that the Smart Client way?

Design Matters
Provide a solution that allows Windows Forms
and Windows Presentation Foundation (WPF) to
coexist within the context of a single, hybrid
application
Spice up your existing Windows Forms application
with WPF content
Add Windows Forms Line of Business controls to your
WPF application
Developer can interact fully across technologies
End user cannot detect technology transitions
Drag and drop WPF user controls directly onto
your Forms
Live preview of the WPF hosted content
Edit content using the best designer for the job
WindowsForms designer for Form layout
WPF UserControl editor for WPF content
Hosted Control Model
