Remarks

Note

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

This class provides dynamic custom property information for a role property.

An ElementTypeDescriptor for a model element can return a collection of property descriptors for the properties of that model element. This collection can contain property descriptors for certain of the links in which the element is a role player. These property descriptors are instances of this class. For more information, see Defining Domain Relationships and the following methods of the ElementTypeDescriptor class: CreateRolePlayerPropertyDescriptor, GetDisplayProperties, and ShouldCreateRolePlayerPropertyDescriptor.

To create a customized role property descriptor, inherit from this class and override one or more of the members.
