1. Developing applications that use system types and collections (15 percent)

A .Manage data in a .NET Framework application by using the .NET Framework 2.0 system types. (Refer System namespace)

•Value types ( VB.Net )
•Nullable type (VB.Net)
•Reference types
•Attributes
•Generic types (VB.Net)
•Exception classes (VB.Net)
•Boxing and UnBoxing (VB.Net)
•TypeForwardedToAttribute Class

B.Manage a group of associated data in a .NET Framework application by using collections. (Refer System.Collections namespace)
