Fully Qualified Type Name in Silverlight

You can ignore the Culture and PublicKey, and they will be defaulted to "neutral" and "null" respectively. However, you must have the following three components in order for Type.GetType(typename) to return you the correct type (otherwise, you will get a Null/Nothing, which is very frustrating).
1. FullName (Namespace + Class name, etc. Complicated when it is a nested class, or generic class, etc.)
2. Assembly
3. Version
An example is:
"DMS.RuleEditor.ViewModel.Logical, RuleEditorViewModel, Version=1.0.0.0"
