Answer 1

http://webservices.amazon.com/AWSECommerceService/AWSECommerceService.wsdl Create a proxy using svcutil.exe for above given url and then this is the Method to GetBookByISBN. AmazonBook is my cutom DTO you have to create you own.

public static AmazonBook GetBookByISBN(string ISBN)
    {
        WebConfigHelper wch = new WebConfigHelper("AWSSettings");
        AmazonBook book = null;
        string AWSAccessKeyId = wch["AccessKey"];
        string AssociateTag = wch["AssociateTag"];
        string AWSSecKey = wch["SecretKey"];

        BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);
        binding.MaxReceivedMessageSize = int.MaxValue;

        AWSECommerceServicePortTypeClient client = new AWSECommerceServicePortTypeClient(
            binding,
            new EndpointAddress("https://webservices.amazon.com/onca/soap?Service=AWSECommerceService"));

        // add authentication to the ECS client
        client.ChannelFactory.Endpoint.Behaviors.Add(new AmazonSigningEndpointBehavior(AWSAccessKeyId, AWSSecKey));


        ItemSearchRequest request = new ItemSearchRequest();
        request.SearchIndex = "Books";
        request.Power = "ISBN:" + ISBN.Trim();
        request.ResponseGroup = new string[] { "Large" };
        request.Sort = "salesrank";

        ItemSearchRequest[] requests = new ItemSearchRequest[] { request };

        ItemSearch itemSearch = new ItemSearch();
        itemSearch.AWSAccessKeyId = AWSAccessKeyId;
        itemSearch.AssociateTag = AssociateTag;
        itemSearch.Request = requests;


        try
        {
            ItemSearchResponse response = client.ItemSearch(itemSearch);
            Items info = response.Items[0];
            if (info.Item != null)
            {
                Item[] items = info.Item;
                if (items.Length == 1)
                {
                    book = new AmazonBook(items[0]);
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
        return book;


    }

You can use this library Nager.AmazonProductAdvertising you can install it easy with nuget. The library also support .NET Standard 2.0

You can find here a asp.net Website implementation example

PM> Install-Package Nager.AmazonProductAdvertising

Short example:

var authentication = new AmazonAuthentication();
authentication.AccessKey = "accesskey";
authentication.SecretKey = "secretkey";

var wrapper = new AmazonWrapper(authentication, AmazonEndpoint.US);
//The Lord of the Rings
var result = wrapper.Lookup("978-0261102385");
