The type of the object to compare.This type parameter is contravariant. That is, you can use either the type you specified or any type that is less derived. For more information about covariance and contravariance, see [2678dc63-c7f9-4590-9ddc-0a4df684d42e].

Remarks
None of the methods in the .NET Framework for Windows Phone class library have a Predicate<(Of <(T>)>) delegate as a parameter. The Predicate<(Of <(T>)>) delegate exists primarily to support the infrastructure, but you can still use it to create custom methods that use predicates.
