Trackable DTO’s: Taking N-Tier a Step Further with EF4
If you look closely at the ObjectChangeTracker class that is generated for the client, you’ll see that it maintains metadata for navigation properties with items that have been added or removed, as well as original values and extended properties. Each entity has an ObjectState property indicating its change state (Unchanged, Added, Modified, Deleted), which is sent to the service where it is used to perform inserts, updates and deletes against a database. Download code for this post here .

Architecture or Design?
The term “software design” is often used to describe the external properties of the software, how it looks, feels, perhaps the features it offers. I mentioned the A word in my last post ( Are there any System Analysts out there? ). As regular readers might have noticed, I have over the years of this blog taken the odd pot-shot at Architects . But

Using Model – View – ViewModel with Silverlight
Think of the Model as the data and the business rules. The Model The Model I am using is very simple and has two read-write properties, FirstName and LastName, and a single read-only property, FullName. The FullName property represents some business rule on how a name should be formatted. And the View uses data binding to set the The View – Model – ViewModel design pattern, also known as MVVM, is getting more popular these days. I

Paging with the Silverlight RIA services DomainDataSource
Of course it is just a matter of setting properties so doing so from code is easy enough.
Using the declarative DomainDataSource that is part of the upcoming Silverlight 3 RIA services makes it quite easy to work with data. All you need to do is add a DomainDataSource control to the the XAML, point it to the generated DomainContext class (in this case NorthwindContext) and tell it which method to use to load the data from the web service(in this case LoadCustomers).

Rehosting the Workflow Designer in WF4
This exposes the actual design surface through the View property and the linked property sheet through the PropertyInspectorView property. Both these properties point to ready to use WPF UIElement’s so, as long as the host used WPF, adding them to a form is easy. Note: This blog post is written using the .NET NET framework 4.0

Getting started with Windows Workflow Foundation 4
When we open the property sheet with the WriteLine activity selected we see there are just three properties: the DisplayName, the Text and the TextWriter. The DisplayName is actually the name used on the design surface and used during the design of the workflow. The Text property contains the text we want to print. In the property sheet we see a textbox with the text “ ”. As you may have heard Windows Workflow Foundation 4 is not an upgrade from Windows Workflow Foundation 3 (or 3.5). The version numbers might suggest that the previous version was quite

TryCatch activity in WF4
Besides the FaultSource you also get the Fault and a FaultHandler property which will tell you if there is a TryCatch activity that might handle it. I can’t say I am a fan of the way the TryCatch activity is implemented in Windows Workflow Foundation 4. For starters there is a Finally block where you can add some activities you want to execute. Sounds nice and very much like the try/catch/finally code construct we have in C# or Visual Basic.
