Microsoft.VisualStudio.Modeling Namespace

The Modeling namespace deals with additions, deletions, and modifications of elements and links when a model is created or modified.

The Modeling namespace classes allow your code to create and modify elements and links within transactions. The Store is the class that represents the contents (elements and links) of a model in memory. Whenever you programmatically make changes to a model, these changes must be done within a Transaction.

You can define rules that are run when certain things happen, such as an element or a link being added, changed, or deleted.

You can also subscribe to be notified when an event such as a transaction being rolled back occurs.

The difference between rules and events is that rules are fired within a transaction while events are fired after a transaction is committed.
