how can i use the file that is generated by xsd.exe in windows 10 universal app

Question

I am generating .cs files from .xsd files using xsd.exe. But when I am adding the files to windows 10 universal blank app, I was getting error as "missing an assembly reference" for System.SerializableAttribute() and System.ComponentModel.DesignerCategoryAttribute(‌​"‌​code"). I fixed this by @t.ouvre's trick. Then there were no errors in any of the particular line of the code but when i am building the code i am getting an error saying that " Cannot find type System.ComponentModel.MarshalByValueComponent in module System.dll" and it doesn't specify exactly where the error is. How can I use the file generated by xsd.exe in windows 10 universal app? What are all the things that I need to do with the file to use it for serialization and deserialization (using DataContractSerializer in UWP)

You can fake missing classes (System.SerializableAttribute(),System.ComponentModel.DesignerCategoryAttribute), just add new files with theses classes definitions :

namespace System
{
    internal class SerializableAttribute : Attribute
    {
    }
}
namespace System.ComponentModel
{
    internal class DesignerCategoryAttribute : Attribute
    {
        public DesignerCategoryAttribute(string _) { }
    }
}

for serialization and deserialization, you have to use System.Runtime.Serialization.DataContractSerializer. For example :

DataContractSerializer serializer = new DataContractSerializer(typeof(request));
var r = new request { version = "test" };

using (MemoryStream ms = new MemoryStream())
{
    serializer.WriteObject(ms, r);
    ms.Seek(0, SeekOrigin.Begin);
    using (var sr = new StreamReader(ms))
    {
        string xmlContent = sr.ReadToEnd();
        Debug.WriteLine(xmlContent);
        ms.Seek(0, SeekOrigin.Begin);
        using (XmlReader reader = XmlReader.Create(sr))
        {
            var deserialized = serializer.ReadObject(reader) as request;
            if (deserialized != null && deserialized.version == r.version)
            {
                Debug.WriteLine("ok");
            }
        }
    }
}
