Exchange ews managed api create item in public folder

Question

I have written the following VB code to create a contact using the Exchange managed API. It creates a contact in the default "contacts" folder within the inbox. However I need to know how to modify it to save the contact into a public folder. If anyone knows how to do it in C# feel free to reply as I can translate back to VB.

Function create_contact()
    ServicePointManager.ServerCertificateValidationCallback = New RemoteCertificateValidationCallback(AddressOf ValidateCertificate)
    Dim service As New ExchangeService(requestedServerVersion:=ExchangeVersion.Exchange2007_SP1)
    'Add a valid EWS service end point here or user Autodiscover

    service.Url = New Uri("https://server/ews/exchange.asmx")

    'Add a valid user credentials

    service.Credentials = New WebCredentials("username", "password", "domain")

    'To address the SSL challenge

    ServicePointManager.ServerCertificateValidationCallback = New RemoteCertificateValidationCallback(AddressOf ValidateCertificate)

    Try


        Dim contact As Contact = New Contact(service)

        contact.GivenName = "Brian"
        contact.MiddleName = "David"
        contact.Surname = "Johnson"
        contact.FileAsMapping = FileAsMapping.SurnameCommaGivenName
        contact.Save()



        MsgBox("Contact created!!!")

    Catch ex As Exception

        MsgBox(ex.Message)

    End Try



End Function

You can specify the folder ID as a parameter for Save method of Contact class.

contact.Save(folderId)

Where folderId is an ID of your destionation public folder
