The WCF RIA Services Toolkit consists of a number of out-of-band features that are (currently) not included in the core RIA Services framework. These typically are features that haven t quite reached the maturity required to be full-fledged members of the core RIA Services framework, but are updated frequently and made available for you to use while they gain maturity (without any guarantees that they will work as required, or won t radically change and/or break your code with future updates). By making them available in the toolkit, Microsoft is able to garner feedback from developers and update them accordingly in a timely manner without needing to wait for a new release of the full framework. In turn, Microsoft is providing new features on a regular basis for you to use, much earlier than you would otherwise be able to. At the time of writing, the following features can be found in the WCF RIA Services Toolkit: LinqToSqlDomainService: Unfortunately, there is currently no support for LINQ to SQL models out of the box in the RIA Services framework. However, you can find the LinqToSqlDomainService class in the toolkit (similar to the LinqToEntitiesDomainService in the framework, but for LINQ to SQL) to provide this support. SOAP Endpoint: This enables you to expose a SOAP endpoint for your domain services. JSON Endpoint: This enables you to expose a JSON endpoint for your domain services. ASP.NET DomainDataSource: This is a data source control that enables you to communicate with your domain services in an ASP.NET application or web site.

Note To display or hide interface names on the class designer, right-click on the interface icon and select the Collapse or Expand option.

Now that you have some classes that support the IPointy interface, the next question is how you interact with the new functionality. The most straightforward way to interact with functionality supplied by a given interface is to invoke the members directly from the object level (provided the interface members are not implemented explicitly; more details later in the section Resolving Name Clashes via Explicit Interface Implementation ). For example, consider the following Main() method: static void Main(string[] args) { Console.WriteLine("***** Fun with Interfaces *****\n"); // Call Points property defined by IPointy. Hexagon hex = new Hexagon(); Console.WriteLine("Points: {0}", hex.Points); Console.ReadLine(); } This approach works fine in this particular case, given that you are well aware that the Hexagon type has implemented the interface in question and therefore has a Points property. Other times, however, you may not be able to determine which interfaces are supported by a given type. For example, suppose you have an array containing 50 Shape-compatible types, only some of which support IPointy. Obviously, if you attempt to invoke the Points property on a type that has not implemented IPointy, you receive an error. So how can you dynamically determine if a class or structure supports the correct interface One way to determine at runtime whether a type supports a specific interface is to make use of an explicit cast. If the type does not support the requested interface, you receive an InvalidCastException. To handle this possibility gracefully, use structured exception handling as in the following example: static void Main(string[] args) { ... // Catch a possible InvalidCastException. Circle c = new Circle("Lisa"); IPointy itfPt = null; try { itfPt = (IPointy)c; Console.WriteLine(itfPt.Points); } catch (InvalidCastException e) { Console.WriteLine(e.Message); }

If you wish to build a truly prim-and-proper custom exception class, you would want to make sure your type adheres to the exception-centric .NET best practices. Specifically, this requires that your custom exception:

Console.ReadLine(); } While you could use try/catch logic and hope for the best, it would be ideal to determine which interfaces are supported before invoking the interface members in the first place. Let s see two ways of doing so.
