  1. I'm using the MongoClient in my c# console application to connect to MongoDB

https://github.com/mongodb/mongo-csharp-driver/releases/tag/v2.0.0-rc0

  1. My code

      class Program
       {
           static void Main(string[] args)
           {
            const string connectionString = "mongodb://localhost:27017";
    
            // Create a MongoClient object by using the connection string
            var client = new MongoClient(connectionString);
    
            //Use the MongoClient to access the server
            var database = client.GetDatabase("test");
    
            var collection = database.GetCollection<Entity>("entities");
    
            var entity = new Entity { Name = "Tom" };
            collection.InsertOneAsync(entity);
            var id = entity._id;          
        }
    }
    
    public class Entity
    {
        public ObjectId _id { get; set; }
        public string Name { get; set; }
    }
    
  2. After successfully running the code above, I'm unable to find this record in the MongoDB database using this command:

    db.entities.find().pretty()
    

What's wrong with my code?

This is the method I created for inserting data into MongoDB, which is working fine now.

static async void DoSomethingAsync()
{
    const string connectionString = "mongodb://localhost:27017";

    // Create a MongoClient object by using the connection string
    var client = new MongoClient(connectionString);

    //Use the MongoClient to access the server
    var database = client.GetDatabase("test");

    //get mongodb collection
    var collection = database.GetCollection<Entity>("entities");
    await collection.InsertOneAsync(new Entity { Name = "Jack" });
}
