TypeReference	Optional InternalTypeReference_Type element. Describes a type that is defined in the proxy descriptor file. You must include either a TypeReference or ExternalTypeReference element, but not both.

ExternalTypeReference

Optional ExternalTypeReference_Type element.

Describes a type that is not defined in the proxy descriptor file. You must include either an ExternalTypeReference or TypeReference element, but not both.

TypeReference

Optional InternalTypeReference_Type element.

Parent Elements

Element	Description
Attribute	Represents an attribute of a type, member, or parameter.
Event Element for Class for COMLibrary	Represents an event that is defined in a proxy type for a COM type.

Example

The following example demonstrates a Type element that represents the type of the delegate that handles a proxy event named ColorChanged. The type of the delegate is Microsoft.VisualStudio.Tools.Applications.Samples.ShapeApp.ColorChangedEventHandler. Because the reference to this delegate is in a TypeReference element rather than an ExternalTypeReference element, this delegate must be defined elsewhere in the same proxy descriptor file.

<Event originalName="ColorChanged" isExcluded="false">
  <Type>
    <TypeReference type="Microsoft.VisualStudio.Tools.Applications.Samples.ShapeApp.ColorChangedEventHandler" />
  </Type>
</Event>
