Use the following enumeration members to specify how an InstanceDependencyProperty behaves.
Assembly: Microsoft.Rtc.Workflow (in Microsoft.Rtc.Workflow.dll)
'Declaration Public Enumeration InstanceDependencyPropertyOption 'Usage Dim instance As InstanceDependencyPropertyOption
public enum InstanceDependencyPropertyOption
|Default||Indicates that the property is a read/write property.|
|ReadOnly||Indicates that the propery is read-only.
Read-only properties can set once, either by registering with a default value or by calling SetValue. Calling SetValue once the value is set will throw an exception. Read-only properties are best used when a corresponding .Net property would have been declared readonly. This includes variables containing collections that cannot be set (i.e., the collection object is constant, although the content of the collection can change).
