title: Asp.net MVC type double modelbinder
body: <p>I have an ASP.NET MVC 3 application, which uses the Entity Framework.
  I have a simple database that contains a field of type float, which the entity framework automatically maps to the type double.</p>
  
  <p>In a simple form of editing I try to update the value of this field, with a decimal value.i.e:
  "3.45",or "121.34"</p>
  
  <p>But the MVC always returns a validation error saying that these values ​​are not valid for type double.If I change these values to:"3"and "121",it works....</p>
  
  <p>"3.45" and "121.34" are not valid values ​​for type double?</p>
