title: Change namespace for entire project in VS 2017
body: <p>Previously some of the classes were present in <code>MyProject.Web.Core</code> project, which are moved to <code>MyProject.Model</code> project. However these moved classes have namespace as <code>MyProject.Web.Core</code>. </p>
  
  <p>So, how can I change the namespace for all classes to <code>MyProject.Model</code> as we don't want to update them manually. Is there any option available in VS2017 ?</p>
  
  <p>We have already update the default namespace in project properties, so that will be get applied when new class is added. But, how about for the moved/old classes?</p>
