title: Resharper - how to import all missing namespaces?
body: <p>I replaced the usage of an extension method with Find-Replace, because Resharper unfortunately could't replace it properly. Now, I have 4000 errors in the solution, and all of them are because the namespace for the new method is missing, so I'm in a desperate need of a "fix/import all missing namespaces in the solution" functionality. </p>
  
  <p>Does Resharper or some other tool have such a thing or I'm going to spend the next hours going through the files, pressing ALT+ENTER?</p>
