What steps will reproduce the problem?
1. Run unit test pasted at the bottom of this report.

What is the expected output? What do you see instead?
The test should pass; I see this stack trace instead:

System.ArgumentOutOfRangeException : Specified argument was out of the range of 
valid values.

Debugging the code reveals that the key passed in is -1, the way it's supposed 
to be for dynamic types (NetObjectSerializer.cs, line 16: this.key = 
dynamicType ? -1 : key;)
Here is the line where it breaks when key == -1:
((MetaType)types[key]).Serializer.Write(value, dest);

What version of the product are you using? On what operating system?

I pulled and built the read-only trunk from svn.

Please provide any additional information below.

Here is the body of the unit test that exposes the error:

        [Test]
        public void TestDynamic() {
            var myVal = new TestProto {Value = true};
            byte[] serialized;
            using (var ms = new MemoryStream()) {
                Serializer.Serialize(ms, myVal);
                serialized = ms.ToArray();
            }
            Assert.That(serialized, Is.Not.Null);
        }

        [ProtoContract]
        public class TestProto {
            [ProtoMember(1, DynamicType = true)]
            public object Value { get; internal set; }
        }

This seems to have already been fixed by ongoing tweaking of DynamicType
