.ToHashSet() & net472 targeting

[ig-sinicyn]

.ToHashSet() calls fail for net472 projects

Code

var c = new[] { 1, 2, 3 }.ToHashSet();

Compilation error:

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

Shouldn't this extension method be excluded for net472?
