title: Service Fabric Health Checking
body: <p>Is there an inbuilt health check for service fabric? I have a guest executable written in NET Core 2.2 and utilising the health check feature within it. For example, I have a simple health check that returns unhealthy state:</p>
  
  <pre><code>        services
              .AddHealthChecks()
              .AddCheck&lt;DocumentDbHealthCheck&gt;("cosmos-database");
  
      internal class DocumentDbHealthCheck : IHealthCheck
      {
          public Task&lt;HealthCheckResult&gt; CheckHealthAsync(HealthCheckContext context, CancellationToken cancellationToken = default(CancellationToken))
          {
              return Task.FromResult(HealthCheckResult.Unhealthy());
          }
      }
  </code></pre>
  
  <p>I have hooked this up using:</p>
  
  <pre><code>app.UseHealthChecks(@"/foo/bar/v1/healthcheck");
  </code></pre>
  
  <p>However, when I locally startup my service fabric instance the state is healthy, I was expecting this to be in an errored / unhealthy state. </p>
  
  <p>Is it possible to have service fabric hit the API healthcheck route?</p>
