What needs to be done in order to serialize enums with protobuf-net? I'm getting the below error when serializing a class having an enum property, if the DataMember attribute is removed from the property declaration it works fine. "System.InvalidOperationException: Only data-contract classes (and lists/arrays of such) can be processed" I suspect they are actually 2 different scenarios, but with regard to the code sample added by Andrew, this is because it can't figure out (in advance) what it is going to do with regards to default values (by default, data is treated as optional at the receiver

I have many different schemas, however there are a set of fields which every schema contains. I was wondering if there was a way to have a different schema extend a parent schema and inherit its fields. For example this is what I want: message Parent { required string common1 = 0; optional string common2 = 1; } message Child1 { // can we extend the Parent? // I want common1, common2 to be fields here required int c1 = 2; required string c2 = 3; } message Child2 { // can we extend Parent? // I want common1, common2 to be fields here repeated int c3 = 2; repeated string c4 = 3; } Such that

I am trying to send protobuf data from cpp side to java side. I have multiple message types defined in .proto On Cpp side, I have enums for every message type and I am adding it to the buf output as follows: uint8_t* __temp = (uint8_t*)(buf); *__temp++ = (type) >> 8; *__temp = (type) & 0x00FF; How do I get this 'type' that I have added to the buf, so that I can achieve something like MessageType parseFrom(byte[] data); It is not clear what is the exact requirement. But I assume you are trying to send different types of messages and the the receiver should be able to parse the correct object
