title: Accept multiple parameters for API in .NET Core 2.0 using attribute routing
body: <p>I have an incoming GET request as follows:  </p>
  
  <pre><code>https://localhost:44329/api/scoInfo?activityId=1&amp;studentId=1&amp;timestamp=1527357844844
  </code></pre>
  
  <p>How would I create an endpoint in ASP.net-core that would accept this request.</p>
  
  <p>I have tried different versions of the following and nothing works:</p>
  
  <pre><code>[HttpGet("{activityId: int}/{studentid: int}/{timestamp: int}")]
  [Route("api/ScoInfo/{activityId}/{studentid}/{timestamp}")]
  </code></pre>
