title: EF maps SQL float to decimal
body: <p>I changed a field in my SQL table from decimal to float and selected "Update model from database" in the designer, but the entity still has the field as a decimal, and so I get a complier error "member mapping is not valid"</p>
  
  <p>Why would the update from DB not function correctly? I was expecting the entity to regenerate with a float type.</p>
  
  <p>Thanks</p>
  
  <p>UPDATE: actually I see it should map to double. But I cannot get it to change from decimal when updating.  I guess I shouldn't do it manually as it will be overwritten again later with decimal.</p>
