Designer extensibility

摘要

Aspects of the subject matter described herein relate to designer extensibility. In aspects, a designer package is registered. The designer package includes a component that is able to search for designers that support a given file. After finding one or more designers that support a file, the component creates a control that includes the one or more designers. The component may also include in the control an editor usable to view a text-based representation of the file. After creating the control, the component may return a reference to the control that may be used to host the control. The mechanism also supports finding and creating controls that are not based on files.
