title: How to connect to Cloud Firestore DB with .net core?
body: <p>So far all the <a href="http://googlecloudplatform.github.io/google-cloud-dotnet/docs/Google.Cloud.Firestore/userguide.html" rel="noreferrer">examples</a> of using Google Cloud Firestore with .net show that you connect to your Firestore db by using this command:</p>
  
  <pre><code>FirestoreDb db = FirestoreDb.Create(projectId);
  </code></pre>
  
  <p>But is this skipping the step of authentication? I can't seem to find an example of wiring it up to use a Google service account.  I'm guessing you need to connect using the service account's private_key/private_key_id/client_email?</p>
