title: Difference between 1 succeeded and 1 succeeded or up-to-date in c#
body: <p>I would like to clear one concept.
  In c#,
  when we build(or re-build) a solution,
  We sometimes get
  <code>Build: 1 succeeded</code></p>
  <p>and sometimes,</p>
  <pre><code>Build: 1 succeeded or up-to-date
  </code></pre>
  <p>Ok, I know that something in our code would be not as per logic when we get the latter ans.</p>
  <p>But, what does it mean <code>CONCEPTUALLY</code>?</p>
