Using ASP.NET Authentication in a Web Service with Silverlight

A reader recently asked me to expand on the ASP.NET Authentication + Silverlight concept I started.. Specifically they wanted to do know how they can have a web service that returns different results depending on who calls the service (and what role they are in).  Here is my quick walk through of adding that capability to the Silverlight+ASP.NET AppServices sample. First, let's look at the scenario we are trying to enable.  I wanted to add a "Fire Bob" button. Hopefully, no line of business application has a "fire employee" button, but I thought it showed of the concepts well.   Clearly only managers should be able to fire bob, so the button should be grayed out if you are not logged in or logged in...

How to add Dynamic Data to an Existing Web Site

I've had various people ask me if Dynamic Data can be added to an existing website and I've compiled a list of steps to do this. We hope to add a tooling gesture to Visual Studio in the future to automatically do these steps. Once these steps are complete you can start taking advantage of Dynamic Data functionality in your existing applications. 1) Create a dummy Dynamic Data Website project. Copy the DynamicData directory from it into your existing website. You should also copy the Site.css and Site.master files. The Default.aspx file is optional, it display a menu of tables in your data model, this file is only needed if you plan on having such a menu in your application. 2) You can copy the Global.asax file or if you already have...

ASP.NET DynamicData: An Introductory Demo

I had a bit more time on my travels , so I cooked up this brief introduction to Dynamic Data .  I tried a different approach this time by showing what Dynamic Data adds to our existing data story.  More information on Dynamic Data:  http://asp.net/dynamicdata To do this demo, install Visual Studio 2008 SP1 and the Dynamic Data update . I started off with a new, blank Dynamic Data Web Site But rather than going directly into Dynamic Data features, I thought I'd review were we are today with .NET Framework 3.5 briefly.  Add New Item and select "Linq to Sql Classes" (notice this works nearly the same with Entity Framework Then add a couple of tables from Northwind.  I am using Products, Categories and Suppliers...
