Parameters

first: Type: System.Linq..::.ParallelQuery<(Of <(TFirst>)>)
This parameter is not used.

second: Type: System.Collections.Generic..::.IEnumerable<(Of <(TSecond>)>)
This parameter is not used.

resultSelector: Type: System..::.Func<(Of <(TFirst, TSecond, TResult>)>)
This parameter is not used.

Type Parameters

TFirst: This type parameter is not used.
TSecond: This type parameter is not used.
TResult: This type parameter is not used.

Return Value

This overload always throws a NotSupportedException.

Remarks

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