I need use protobuf in my windows store app and I use this Protobuf port but when I generate classes from proto file seen like not full because I dont have access to .newBuilder()... nad if I use p:lightFramework I still cannot work with .newBuilder()... Anyone can help?

Part of generated code without light framework options

[global::System.Serializable, global::ProtoBuf.ProtoContract(Name=@"Person")]

Part of generated code with light framework options

[global::ProtoBuf.ProtoContract(Name=@"Person")]

Problem is there:(.newBuilder() is not recognized 

CP.ConnectionResponse respp = CP.ConnectionResponse.newBuilder()...

You seem to be using two different libraries at once; in particular, you seem to be following the instructions for protobuf port, but actually using protobuf-net. These are two different libraries, connected only in so much as:

  • they both target .NET
  • they both serialize/deserialize protobuf data

To add context - this is a bit like using JSON.NET but following the instructions for ServiceStack.Text: both can serialize/deserialize JSON, but the API is different.

You need to decide which library you want to use, and follow the instructions for that implementation.

As an aside: for the best performance on a store app / windows phone app with protobuf-net, you may also want to consider using the precompiler - but you should be able to get it working (for a proof-of-concept etc) without this.

I need use protobuf-csharp-port but I already has to worry about the third day and I can not figure it out .( I download Version 2.4.1.521 release binaries only but I cannot generate classes from proto file. I use example and then I got this dl.dropboxusercontent.com/u/40039421/a.PNG – Pavol Franek Jul 17 '13 at 9:19
    
@user2244495 the code in your question, with ProtoBuf.ProtoContractAttribute - that is protobuf-net code. Are you sure you are using the right "protogen" ? However, as for the screenshot - you must include the --proto_path in the same command as when you call protogen – Marc Gravell♦ Jul 17 '13 at 11:02
    
thx for your answer now I can generate classes. I have one question maybe you had similar problem. When I use my generated class in W8 app I get this error dl.dropboxusercontent.com/u/40039421/e.png – Pavol Franek Jul 18 '13 at 7:00
    
@user2244495 well, I'm the protobuf-net guy; that is protobuf port - Jon Skeet is the person you want to ask. But: a TypeInitializationException means that a static constructor threw an exception; look at the .InnerException to see exactly what actually happened – Marc Gravell♦ Jul 18 '13 at 7:19
