Advanced Encryption in Silverlight and .NET Applications

AES encryption is implemented in both Silverlight and .NET run times, using exact same set of classes, primary one being AesManaged class.

Create a Path Using Path Markup Language Silverlight 4 - Video Tutorial

Silverlight supports a powerful and complex mini-language that you can use to describe geometric paths. You use this mini-language when setting a property of type Geometry, such as the Clip property of a UIElement or the Data property of a Path element. In this video, Todd Miranda demonstrates how to manually create a path using Path Markup Language.

RIA Services - Presentation Model & POCO Objects

RIA Services handles any relationship other than Many to Many. If you have a Many to Many you will need to have a linking entity between the two tables.

Each Entity POCO on the server needs to have a primary key (you mark the key(s) with the KeyAttribute). Related entities need a foreign key property and you need to mark the relationships with AssociationAttributes.

RIA Services is good at lazy loading, but you have to manually trigger the loads it will not do it automatically. If you want to load the Companies and the Employees at the same time then you need to decorate the association properties with the IncludeAttribute. If you don't want to include them then you don't. Because RIA Services is based on keys and foreign keys, you can load the Companies up in one load and then later if you want them load up the Employees and the relationships between the two tables will automatically link back on on the client based on the values of the foreign keys.

A few good resources to look at what be documentation of what RIA Services calls a Presentation Model:

and there is a simple example of how the attributes work here:
