title: How do I initialize a Dictionary(Of String, HashSet(Of String)) in VB.NET?
body: <p>I've got an existing <code>String</code> and <code>HashSet(Of String)</code>, but the following code</p>
  
  <pre><code>Dim myDict As New Dictionary(Of String, HashSet(Of String))(myString, myHashSet)
  </code></pre>
  
  <p>yields this Intellisense error: <code>Argument matching parameter 'comparer' narrows from 'System.Collections.Generic.HashSet(Of String)' to 'System.Collections.Generic.IEqualityComparer(Of String)'</code></p>
  
  <p>What's the right way to create this dictionary?</p>
