System.Linq.Enumeration.Chunk - CS0121: The call is ambiguous between the following methods or properties

Line 36 in 3f7ffdd

public static IEnumerable<TSource[]> Chunk<TSource>(this IEnumerable<TSource> source, int size)

I'm creating a brand-new blank console app with dotnet new console. When I try to use the Chunk extension method on a simple array or list, it results in the following error:

Error	CS0121	The call is ambiguous between the following methods or properties: 'System.Linq.Enumerable.Chunk<TSource>(System.Collections.Generic.IEnumerable<TSource>, int)' and 'System.Linq.Enumerable.Chunk<TSource>(System.Collections.Generic.IEnumerable<TSource>, int)'

Can you share a repro, both csproj and cs files?

@stephentoub thanks for the quick reply. I discovered that there was "sample" code polluting the namespace with an alternate implementation of the same extension method name.
