This enumeration contains the values used by IDispatchImplAttribute. SystemDefinedImpl tells the runtime to decide which IDispatch implementation to use. InternalImpl tells .NET to use its own IDispatch implementation, and CompatibleImpl uses an IDispatch implementation that is compatible with OLE automation. If you use this last implementation, it requires static type information. Because this information is automatically generated at runtime, CompatibleImpl may have an adverse impact on performance.

public enum IDispatchImplType {
   SystemDefinedImpl = 0,
   InternalImpl = 1,
   CompatibleImpl = 2
}
