            return View(list);
        }

        public async Task GetUsers()
        {
            var filter = new BsonDocument();
            var collection = Context.Collection();            
            var cursor = await collection.FindAsync(filter);
            while (await cursor.MoveNextAsync())
            {
                var batch = cursor.Current;
                list.AddRange(batch);
            }            
        }
    }

Change your code to

public async Task<ActionResult> Index()
{
   await GetUsersAsync();
   return View(list);
}

public async Task<Context.Collection> GetUsersAsync()
{
    var filter = new BsonDocument();
    var collection = Context.Collection();            
    var cursor = await collection.FindAsync(filter);
    while (await cursor.MoveNextAsync())
    {
       var batch = cursor.Current;
       list.AddRange(batch);
    }      
    return list;      
}
