Authentication and roles
Demo
Summary
> Authentication & roles> Declarative: class / method-level> Integrated into Query / Submit processing
Agenda
> WCF RIA Services in context> A look “under the hood”> Using RIA Services effectively
Using RIA Services effectivelyDo> Require authentication /
roles> Authenticate w/ https
> Utilize query composition> Filter, sort, page
> Consider custom update
> Factor into multiple DomainService classes / libraries
> Handle errors on server
> Use declarative validation
Don’t> Deploy with anon access
> Expose non-essential entities/ operations or allow free-form access to data
> Use a single large DomainService class
Call to action
> Try RIA Services bits> Beta on .NET 3.5 SP1/ VS 2008 /
Silverlight 3> Preview on Dev10 / Silverlight 4 (this will
evolve into V1 RTW)> Give us feedback and join us on forum> Home page
