protobuf-net is a long-standing .NET implementation of Google's "protocol buffers" (ProtoBuf) binary serialization format.

Traditionally, ProtoBuf uses a DSL ("proto2" or "proto3") to define document schemas. Breaking with tradition, protobuf-net doesn't force you to use schemas - being perfectly happy to work with POCO objects. However, if you use schemas, tools should be available to help you generate suitable POCOs from your schema.

protobuf-net has had tools to do this, but they have always been a hack - behind the scenes, "protogen" used Google's "protoc" tool to parse the model and compile it as a protobuf object, then deserialized the binary, then re-serialized it as xml, then ran the xml through xslt stylesheets. It worked, but... damn. This was very bad for cross-platform work: "protoc" is an OS-specific binary executable, and xslt has poor support in .NET cross-platform. Additionally, the tooling had lapsed and "proto3" had neven been implemented. Finally, the generated code has not been updated to use language improvements from multiple C# releases.

As part of protobuf-net 2.3.0, I'm dusting off the DSL tools; aims:

It is far from complete, but: I'm getting there!

Why is this a website?

Because that is just a convenient way for me to play with it. Long term I would expect to have compile-time command-line options that work via dotnet build or whatever you want; I don't have that today. As for "why is this under your personal doamin?": because domain names and hosting cost money, and my own domain already existed. It works.

Holy hell this site is ugly!

Yes. I'm a tools & infrastructure person; I don't do pretty. If you can do better, feel free to submit a PR; the code is right here.
