Solution

  • By default, WCF proxy generation creates arrays for all collection types. So, you can fix this problem by changing your variable assignment to this

    BusinessResponse<Product[]> reponse = client.GetProductList(2);

    You can also change the default collection type generated by the proxy by choosing a collection type in the Advanced Settings (Array, List, ArrayList, etc.)
