Filbert – a BERT serializer for .Net
I spent the last couple of nights and put together a small BERT serializer for .Net called Filbert. What’s BERT? BERT (Binary ERlang Term) is a binary format based on Erlang’s binary serialization format (as used by erlang:term_to_binary/1) but supports a couple of complex types such as boolean, dictionary and time, in additional to …
