title: Binding Double to TextBox
body: <p>I have often used TextBox to bind to Integers without much problem.</p>
  
  <p>However if I try to bind a TextBox to a Double it doesn't work.</p>
  
  <p>When I type 5,85 ( , being my cultures decimalSeperator) I pass 585.0 to the double value.</p>
  
  <p>How is it being converted and what solution could I use to fix this? Would a ValueConverter be the best solution?</p>
