Properties of Elements in UML Sequence Diagrams

In a UML sequence diagram in Visual Studio Ultimate, each element on the diagram has properties. To see the properties of an element, right-click the element on the diagram or in UML Model Explorer and then click Properties. The properties appear in the Properties window.

Note Note

This topic is about the properties of elements in UML sequence diagrams. For more information about how to read UML sequence diagrams, see UML Sequence Diagrams: Reference. For more information about how to draw UML sequence diagrams, see UML Sequence Diagrams: Guidelines.
