title: "Update Model from Database" does not see a type change
body: <p>I have several columns that I changed from Int to BigInt.</p>
  
  <p>I opened up my EF model and did an 'Update Model from Database' and expected to see those columns now be Int64s.  But they are still Int32s.</p>
  
  <p>(I ran it several times just to be sure.)</p>
  
  <p>I double checked my database and the columns are definitely BigInts.</p>
  
  <p>So... does 'Update Model from Database' not work for a change of data type?  Does it need to be manually applied?</p>
