Caution
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 Function SequenceEqual(Of TSource) (first As ParallelQuery(Of TSource), second As IEnumerable(Of TSource)) As Boolean
Type Parameters
- TSource
This type parameter is not used.
Parameters
- first
- ParallelQuery<TSource>
This parameter is not used.
- second
- IEnumerable<TSource>
This parameter is not used.
Returns
This overload always throws a NotSupportedException.
- Attributes
Exceptions
Thrown every time this method is called.
Remarks
This overload exists to disallow usage of SequenceEqual with a left data source of type ParallelQuery<TSource> and a right data source of type IEnumerable<T>. Otherwise, the SequenceEqual operator would appear to be binding to the parallel implementation, but would in reality bind to the sequential implementation.
