DataContractSerializer serializes URI (relative or absolute) as simple string.
Therefore, relative URI that should begins with "/" letter deserializes as
absolute path on Linux.
Of course, on Windows platform this issue is not actual.

Reproducible: Always

Steps to Reproduce:
    public sealed class XmlSerializable
        [DataMember(Name = "Address")]
        private Uri m_address;

        public Uri Address
            get { return m_address; }
            set { m_address = value; }

    static class Program
        static void Main(string[] args)
            var obj = new XmlSerializable { Address = new Uri("/file.f",
UriKind.Relative) };
            var str = new StringBuilder();
            var serializer = new
            using (var writer = new StringWriter(str))
                serializer.WriteObject(new XmlTextWriter(writer), obj);
            using (var reader = new StringReader(str.ToString()))
                obj = serializer.ReadObject(new XmlTextReader(reader)) as
Actual Results:  
obj.Address.IsAbsoluteUri is True

Expected Results:  
obj.Address.IsAbsoluteUri is False

Seems like a deadlock. Because serialized form of relative URI is ambiguous
with relative URI and absolute Linux file path.
But small trick can resolve this situation:
1. new Uri("/file.f", UriKind.Relative) instance should be serialized as
"/file.f" string;
2. new Uri("/file.f", UriKind.Absolute) instance should be serialized as
"file:///file.f" string.
