C# Stripe create customer with default payment method not working

In my workflow I am creating a new customer with a valid payment method and want to set that as default (to apply to subscription billing)

Based on the docs it seems if I'm using PaymentsIntent I need to set DefaultPaymentMethod inside InvoiceSettings and IntelliSense matches everything up as expected. https://stripe.com/docs/api/customers/create#create_customer-invoice_settings-default_payment_method

When I actually create the options object (not even making the Create call) I get the below error

{System.NullReferenceException: Object reference not set to an instance of an object. at ... [offending code below]

var customerOptions = new CustomerCreateOptions
{
    Email = user.Email,
    Name = user.FirstName + ' ' + user.LastName,
    PaymentMethod = model.payment_method,
    InvoiceSettings =
    {
        DefaultPaymentMethod = model.payment_method
    }
};

If I remove the InvoiceSettings param everything works perfectly, except their payment method is not set as default. I have also tried with null in DefaultPaymentMethod, same error.

How can I, during customer creation, set their payment method as default?

You'll need to initialize an instance of CustomerInvoiceSettingsOptions to pass as the InvoiceSettings which you can do with the following: 

var customerOptions = new CustomerCreateOptions
{
    Email = user.Email,
    Name = user.FirstName + ' ' + user.LastName,
    PaymentMethod = model.payment_method,
    InvoiceSettings = new CustomerInvoiceSettingsOptions
    {
        DefaultPaymentMethod = model.payment_method
    }
};
