One or both of the parameters are null. |
If a previous association has been made for the type parameter using the CreateAssociation method, then the GetAssociation method returns the correct secondary object to invoke for the requested type. Otherwise, GetAssociation searches for a compatible designer for type and returns the designer if one is found. This method never returns null.
A WeakReference is used to maintain the association between the primary and secondary object; therefore, this method does not prevent either the primary or secondary object from being finalized and reclaimed by garbage collection.
