What steps will reproduce the problem?
1. Run the supplied code.
2. Notice the newDTO object does not have any value for property, Data
3.

What is the expected output? What do you see instead?
Expect the Data property to be deserialized properly.  I may be missing 
something with how ProtoBuf works.

What version of the product are you using? On what operating system?
v.2.0.0.480
Windows 7

This issue can be fixed using a backing property as shown below.

[ProtoMember(1)]
private byte[] _data
{
    get;
    set;
}

public float[] Data
{
    get 
    { 
        return Array.ConvertAll<byte, float>(_data, b => Convert.ToSingle(b)*0.1f); 
    }
}

This ensures the wire data is only a byte array, but the client has access to 
the float array containing the correct values.  

Additionally, the memory stream should be seek to 0 before deserializing in the 
provider example.

    Serializer.Serialize(ms, dto);
    ms.Seek(0, SeekOrigin.Begin) // ADDED
    var newDTO = Serializer.Deserialize<DTO>(ms);
    Console.Read();
