The way this works with WS-Security based services is that WIF passes the name/namespace of the incoming token to WIF’s security token handler collection.

In the next post I will show you how to implement that for WCF – including full source code and samples. WIF as it exists today is optimized for web applications (passive/WS-Federation) and SOAP based services (active/WS-Trust). While there is limited support for WCF WebServiceHost based services (for standard credential types like Windows and Basic), there is no ready to use plumbing for RESTful services that do authentication based on tokens. But after all, the F in WIF stands for Foundation. www.leastprivilege.com - Tuesday, November 15, 2011 | -

And the BackgroundWorker component lets you write events handlers that are executed on the UI thread when reporting progress or completion. protected void Notify ( EventHandler < NotificationEventArgs > handler, NotificationEventArgs e) { if (handler != null ) { InternalNotify(() => handler( this , e)); } } protected void Notify<TOutgoing> ( EventHandler < NotificationEventArgs <TOutgoing>> handler, NotificationEventArgs <TOutgoing> e) { if (handler != Technical MVVM Silverlight Tony and Zuzana's World - Saturday, January 29, 2011 - WF and ASP.NET - A Few Gotchas
See the sample code referenced at the end of this post for an illustration of the issue, and one potential solution using thread events. Again, see the sample code for an illustration of the issue and one possible resolution. given the synchronous nature of ASP.NET request processing (setting aside async ASP.NET handlers for the moment) I can't generally recommend the use of async activities in workflows used inside ASP.NET. Here's the sample code I refer to above, that illustrates what I'm describing here (requires VS.NET 2008 beta 2). But there's the rub. Enjoy! There Must Be Some Mistake - Monday, October 1, 2007 - Using Model – View – ViewModel with Silverlight
Even thought the UI technology used doesn't change the basic MVVM pattern there are some subtle differences, like not easily being able to use ICommand in Silverlight, so I decided to create a small Silverlight sample. know it is a bit of a lame business rule but it is just a sample. If you need an event handler in your code behind, like the button click, make it a single line and pass the request onto the ViewModel. The View – Model – ViewModel design pattern, also known as MVVM, is getting more popular these days. The View is data bound to a ViewModel. 11: {. 13: set.

Entities are persisted to the Northwind sample database (using SQL Server 2008 Express) through an ADO.NET Entity Data Model. Wire up event handlers in the View code-behind to handle notifications from the ViewModel. Great news! have just published an online tutorial and screencast for using the Simple MVVM Toolkit to build Real-World MVVM Apps with WCF RIA Services.
