I ended up with serialization issues. The solution is to use a standard Emitter and add metadata to the message. For example, this class […]
The XMPP Component framework is coming on nicely. It can connect and send/receive messages: Using C# again is a joy. I absolutely love the dynamic capabilities. For example, in this factory method, Ping is dynamically added – it is not a property: Which produces the following XML: Eventually Ping will be its own subpacket, but […]

This is referred to as a non-denotable type, it is inferred as the type of the expression that is assigned. In this case, the type is […]

I’m currently working on an XMPP library which parses a received XMPP Stanza into a class named BvElement. Abstracting from BvElement are classes such as IQ, […]
