- At the project you just created, go to Firestore Database and create a collection you want:

- Next, go to the project setting:

- At tab Service account generate your private key.

Step 2:

- Create a C# project.

- Use Nuget to install following packages:

- Create folder to store private key.

- Finally, the code to make everything run:

using Google.Apis.Auth.OAuth2;

using Google.Cloud.Firestore;

using Google.Cloud.Firestore.V1;

using Google.Cloud.Storage.V1;

using Grpc.Auth;

using Grpc.Core;

using System;

using System.Collections.Generic;

using System.IO;

using System.Threading.Tasks;

namespace FireBaseConnect

{

    class Program

    {

        static void Main(string[] args)

        {

            MyFireStore myfs = new MyFireStore();

            myfs.GetLicense().Wait();

        }

    }

    class MyFireStore

    {

        string jsonPath = "Your Json Path";

        string projectId = "ProjectId in your private key file";

        FirestoreDb db;

        public MyFireStore()

        {

            using StreamReader r = new StreamReader(jsonPath);

            string json = r.ReadToEnd();

            db = new FirestoreDbBuilder

            {

                ProjectId = projectId,

                JsonCredentials = json

            }.Build();

        }

        public async Task GetLicense()

        {

            // [START fs_get_all]

            CollectionReference usersRef = db.Collection("Licenses");

            QuerySnapshot snapshot = await usersRef.GetSnapshotAsync();

            foreach (DocumentSnapshot document in snapshot.Documents)

            {

                Console.WriteLine("User: {0}", document.Id);

                Dictionary<string, object> documentDictionary = document.ToDictionary();

                Console.WriteLine("First: {0}", documentDictionary["license_id"]);

            }

            // [END fs_get_all]

        }

    }
