Resolved by updating the references to the Json library inside all of the projects in the solution.

I'm getting this error in my existing projects (latest nightly build):

Me too.

Here are the offending code fragments :)...

Dictionary<string, string> dargs = new Dictionary<string, string>();
        dargs.Add("typeSourceID", Guid.NewGuid().ToString());
        dargs.Add("typeSourceID2", Guid.NewGuid().ToString());

        Command testCommand = new Command("command", dargs);
The testCommand is the instance that's passed to serialize. Get the same result if I try and pass in a dynamic type.

?
Thanks,
Dave G
