Question

Is anyone aware of any issues when using ProtoBuf-Net to serialize/deserialize between compact framework and the full .Net framework? I have a class called LogData that I am se

Easy one: you use:

var buffer = ms.GetBuffer();

And then buffer.Length. That means you are using the oversized, padded buffer. If you do that you need to use ms.Length, which will tell you the actual length. Alternatively, ms.ToArray() may be used, but that involves an extra copy.

My advice: keep using GetBuffer(), but only write ms.Length bytes, not buffer.Length bytes.

Once you have removed these extra incorrect zeros, I expect you'll find it works.
