title: Google.Cloud.Firestore not writing data to firestore emulator
body: <p>I'm trying to write data from my local environment (running on iis on my machine) to my Google Firestore emulator. The code runs, doesn't throw an error BUT the data doesn't seem to be being written to the Firestore emulator.</p>
  <p>Using firebase CLI tools v8.6.0
  Google.Cloud.Firestore v2.1.0</p>
  <pre><code>    string project = ConfigurationManager.AppSettings[&quot;firestore_projectid&quot;];
      Environment.SetEnvironmentVariable(&quot;FIRESTORE_EMULATOR_HOST&quot;, &quot;localhost:8080&quot;);
      FirestoreDb db = new FirestoreDbBuilder
          {
              ProjectId = project,
              EmulatorDetection = Google.Api.Gax.EmulatorDetection.EmulatorOnly
                
          }.Build();
  
      var dto = await GetLiveStreamDto();
  
      DocumentReference docRef = db
          .Collection(&quot;Events&quot;)
          .Document(&quot;123456789&quot;)
           
  
      await docRef.SetAsync(dto, SetOptions.MergeAll);
  </code></pre>
