<ExtensionAttribute> <ObsoleteAttribute("The second data source of a binary operator must be of type System.Linq.ParallelQuery<T> rather than System.Collections.Generic.IEnumerable<T>. To fix this problem, use the AsParallel() extension method to convert the right data source to System.Linq.ParallelQuery<T>.")> Public Shared Function SequenceEqual(Of TSource) ( first As ParallelQuery(Of TSource), second As IEnumerable(Of TSource), comparer As IEqualityComparer(Of TSource) ) As Boolean

This overload exists to disallow usage of SequenceEqual with a left data source of type ParallelQuery(Of TSource) and a right data source of type IEnumerable(Of T). Otherwise, the SequenceEqual operator would appear to be binding to the parallel implementation, but would in reality bind to sequential implementation.
