TypeReference	Optional ArrayInternalTypeReference_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 ArrayExternalTypeReference_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 ArrayInternalTypeReference_Type element.

Example

The following example demonstrates a ReturnType element that represents the type of the return value of a method named Load. The type of the return value is a Microsoft.VisualStudio.Tools.Applications.Samples.ShapeApp.IShape interface. Because the reference to this interface is in a TypeReference element rather than an ExternalTypeReference element, this interface must be defined elsewhere in the same proxy descriptor file.

<Method originalName="Load" isExcluded="false">
  <Parameter originalName="savedState">
    <Type>
      <ExternalTypeReference isInterface="false" type="System.Byte" arrayInfo="[]" />
    </Type>
  </Parameter>
  <ReturnType>
    <TypeReference type="Microsoft.VisualStudio.Tools.Applications.Samples.ShapeApp.IShape" />
  </ReturnType>
</Method>
