title: How to use a prefix "N" in LINQ query?
body: <p>I know how to use a prefix "N" in raw SQL query. (For unicode string)</p>
  
  <p>But how to use a prefix N in LINQ query? any suggestion?</p>
  
  <p>------------update------------</p>
  
  <p>Below is the log generated by LINQ:</p>
  
  <pre><code>UPDATE [dbo].[Table1]
  SET [Content] = @p1
  WHERE ([ID] = @p0)
  -- @p0: Input BigInt (Size = -1; Prec = 0; Scale = 0) [3]
  -- @p1: Input Text (Size = -1; Prec = 0; Scale = 0) [こんにちは]
  </code></pre>
  
  <p>There's no N in the above generated SQL statement.</p>
  
  <p>(Note I've set datatype of <code>Content</code> as <code>nvarchar</code>) </p>
