title: Concatenating string to integer
body: <p>Please see the code below:</p>
  
  <pre><code>Dim str1 As String="Test"
  Dim int1 As Integer = 1
  Dim str2 = str1 &amp; int1
  </code></pre>
  
  <p>Should int1 be casted into a string before it is concatenated or does it make no difference?</p>
  
  <p>I have recently turned OPTION STRICT ON in a VB.NET app</p>
