Property Value

Type: System.Collections.Generic.IList<Type>
A list of service types used to convert the unmanaged QueryService method call, in which a service GUID is specified, into a managed GetService method call, in which a managed type is specified.

Remarks

When exposing a managed IServiceProvider object to unmanaged code as the unmanaged IServiceProvider interface, a problem arises in that the unmanaged code will request a service using a service GUID. The managed implementation cannot delegate to the GetService method without first converting this into the managed type. A list of possible service types must be provided so it can search this list for types with a GUID equal to the service GUID.
