I am trying to follow simple steps in the C# driver Quick start but I am hitting a major road block because the driver won't create an ID for my Id public property.

If I understand the docs correctly the driver should use the StringIdGenerator to generate an ID for my

public string Id

property on my models.

I posted a question on SO about this:
http://stackoverflow.com/questions/37361002/mongodb-2-0-c-sharp-driver-not-creating-id-on-inserts

Since I posted the question I also attached [BsonId] attribute to the property if that would made any difference but it still resulted in null ID being used with InsertOne() which at the 2nd retry results in

A bulk write operation resulted in one or more errors.
E11000 duplicate key error collection: testdb.Customer index: id dup key: { : null }

(obviously).

I also tried registering a class map simply with

BsonClassMap.RegisterClassMap<Customer>();

and it still would not create a value for the Id property.
