    /// <summary>Snippet for ValidateAddressAsync</summary>
    /// <remarks>
    /// This snippet has been automatically generated and should be regarded as a code template only.
    /// It will require modifications to work:
    /// - It may require correct/in-range values for request initialization.
    /// - It may require specifying regional endpoints when creating the service client as shown in
    /// </remarks>
    public async Task ValidateAddressRequestObjectAsync()
        // Create client
        AddressValidationClient addressValidationClient = await AddressValidationClient.CreateAsync();
        // Initialize request argument(s)
        ValidateAddressRequest request = new ValidateAddressRequest
            Address = new PostalAddress(),
            PreviousResponseId = "",
            EnableUspsCass = false,
