title: How to include a razor page to another razor page?
body: <p>I'd like to know how to include another razor page in running razor view just as PHP's "include" term. It can be considered as partial classes. Half of work is done at a.cshtml and the other half of works are done at b.cshtml. But in reality two of them are built as one razor page.  </p>
  
  <p>Any ideas will be appreciated...</p>
