This Intersect overload should never be called. This method is marked as obsolete and always throws NotSupportedException when called.

Namespace: System.Linq
Assembly: System.Threading (in System.Threading.dll)

public static ParallelQuery<TSource> Intersect<TSource>(
	ParallelQuery<TSource> first,

)

Parameters

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

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

Type Parameters

TSource: This type parameter is not used.

Return Value

This overload always throws a NotSupportedException.

Remarks

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