Remarks

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.

Observação

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.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
