public-broadcasting's Issues

Caching of already Used Types

When serializing 100.000 instances of the same type (with different values) public-broadcasting takes around 12 seconds. Using protobuf directly (with the classes annotated with [ProtoMember] and etc.) the same experiment takes 0.79 seconds. Deserialization follows the same pattern.

It doesn't seem like public-broadcasting is caching the envelopes it is creating and so it is recreating them every time (something that is expensive).

[InvalidOperationException: Unexpected sub-type: System.String]

Not sure if this is publicbroadcasting or protobuf, but this is the stack trace:

[InvalidOperationException: Unexpected sub-type: System.String]

   PublicBroadcasting.Serializer.Serialize(T obj) in c:\Users\kmontrose\Dropbox\PublicBroadcasting\PublicBroadcasting\Serializer.cs:34

The object I'm trying to serialize looks like:

public class ActionSettings
{
    public string ActionName { get; set; }
    public string ControllerName { get; set; }
    public RouteValueDictionary RouteValues { get; set; }
}

Hope this helps and please let me know if I can provide any other details

ArgumentNullException while deserializing an object

I'll try to work on a reliable reproduction, but in the mean time, this is the stack trace:

[ArgumentNullException: Value cannot be null.
