Serializing dynamic values doesn't seem to work in release 580

[GoogleCodeExporter]

Here is the code to reproduce it:

[ProtoContract]
class TestClass
{
  [ProtoMember(1, DynamicType = true)]
  public object Property1 { get; set; }
}

[Test]
public void TestDecimal()
{
  TestClass testClass = new TestClass {Property1 = 1d};
  using (var file = File.Create("test.txt"))
  {
    Serializer.Serialize(file, testClass);
  }

}

The error is:

System.InvalidOperationException : Dynamic type is not a contract-type: Double

I'm having the same problem... is there some known workaround?

Hi.

I'm having the same problem on the release 640.
Double is not the only type which is "not a contract-type".
There is the same issue with DateTime or Integer.
