Parameters

providerHandles

IList<Lazy<TExtensionFactory,TMetadataView>>

Lazy references that will be evaluated.

dataContentType

IContentType

Target content type.

getter

Func<TExtensionFactory,TExtensionInstance>

Delegate which constructs an instance of the extension from the best matching element of providerHandles.

contentTypeRegistryService

IContentTypeRegistryService

Instance of IContentTypeRegistryService which orders content types.
