Why choosing WSS as a Dev Platform?

End users can create and customize applications to a certain extent without the need of a

Database or System admin, or Web developer

Increased productivity with existing elements

Auditing, ChangeLog, Search, Alerts, Web ServicesData lists and document libraries incl. events and RSS

Integration with Office ClientsScalable platform enables Software+Services scenariosLeverage existing .NET and ASP.NET skillsWeb 2.0 with ASP.NET AJAX and SilverlightCustomer may require „runs on SharePoint“

Querying Lists

Single-list query: SPQueryXML based (CAML Query)

Community Tool: Caml Query Builder can be helpful

New in WSS 3.0SPSiteDataQuery classCross-site, multiple list queriesIndexed fields

LINQ and SharePoint

If you do a lot of list queries: evaluate LINQ to ObjectsLINQ is especially interesting when you need to join lists

var qry = from SPListItem cust in myCustomerList.Items join SPListItem docs in myDocLib.Items on (string)cust["Title"] equals (string)docs["Customer"]

select new { Customer = (string)cust["Title"], DocName = (string)docs[“DocName"], Year = (double)docs["FiscalYear"] };

List Events

Supported on regular lists as well as document librariesAccessing the current list item

prop.BeforeProperties (only doc libs)prop.AfterProperties

Performance

SPSite and SPWeb are managed wrappers (2 KB) to unmanaged classes (1 - 2 MB)Always use Dispose() or the using clause

Small managed objects don’t put pressure on garbage collector (GC) don’t rely on GC!
