I am trying to convert one model into another model that is a slightly different format. I was thinking I could do this in one line without a foreach by using LINQ however I keep running into an error about conversion of types. Here is my code:

                    ToRecipients = new List<Recipient>().AddRange<Recipient>(email.To.Select(contact => new Recipient
                    {
                        EmailAddress = new EmailAddress
                        {
                            Address = contact.EmailAddress,
                        },
                    }));

The error I am running into is :

Argument 2: cannot convert from 'System.Collections.Generic.IEnumerable<Microsoft.Graph.Models.Recipient>' to 'System.ReadOnlySpan<Microsoft.Graph.Models.Recipient>'CS1503

I am not sure what exactly I am doing wrong here as it seemed straight forward. I am looping through my email model and creating a new ms graph recipient object which is returning to the range. Any help would be appreciated!
