This repo was originally exported from http://code.google.com/p/protobuf-csharp-port, and represents the latest "legacy" version of protobuf-csharp-port.
This project has now been folded into the main Google Protocol Buffers project, and is being revamped to support proto3. It is not expected to be fully backwardly-compatible with the code in this repo - in particular, some of the C#-specific options may not be supported in the new codebase, and some of the generated code may differ. A new major version offers an opportunity to spring-clean, as it were.
This repo exists as an acknowledgement that not everyone will want to immediately use the newer codebase, and that they may wish to make changes to the legacy codebase. I do not expect to make any changes within this repo, but it can be forked for further changes.
因为用了Google.ProtocolBuffers 2.4.1.555，但是它不支持.net core；新的Google.ProtoBuf虽然支持.net core，但是和老版本的SDK差别较大，又不想改业务代码。所以只好找到这个源代码修改下让其能够支持.net core。
只是增加了项目文件和解决访问文件：
ProtocolBuffersLibrary.NETSTANDARD.sln
ProtocolBuffers.NETSTANDARD.csproj
ProtocolBuffers.Serialization.NETSTANDARD.csproj
ProtocolBuffers.Test.NETSTANDARD.csproj
如上，编译了Google.ProtocolBuffers和Google.ProtocolBuffers.Serialization，并通过了单元测试。
这个包也发布到了NuGet，可以直接安装，地址：
