This directory contains the C# Protocol Buffers runtime library. |
|
|
|
Status: Beta - ready for external testing |
|
========================================= |
|
|
|
Usage |
|
===== |
|
|
|
The easiest way how to use C# protobufs is via the `Google.Protobuf` |
|
NuGet package. Just add the NuGet package to your VS project. |
|
|
|
Besides C# runtime library, the NuGet package also contains |
|
precompiled version of `protoc.exe` and a copy of well known `.proto` |
|
files under the package's `tools` directory. |
|
|
|
To generate C# files from your `.proto` files, invoke `protoc` with the |
|
`--csharp_out` option. |
|
|
|
Supported platforms |
|
=================== |
|
|
|
The runtime library is built as a portable class library, supporting: |
|
|
|
- .NET 4.5 |
|
- Windows 8 |
|
- Windows Phone Silverlight 8 |
|
- Windows Phone 8.1 |
|
- .NET Core |
|
|
|
You should be able to use Protocol Buffers in Visual Studio 2012 and |
|
all later versions. This includes all code generated by `protoc`, |
|
which only uses features from C# 3 and earlier. |
|
|
|
Building |
|
======== |
|
|
|
Open the `src/Google.Protobuf.sln` solution in Visual Studio 2015 or |
|
later. You should be able to run the NUnit test from Test Explorer |
|
(you might need to install NUnit Visual Studio add-in). |
|
|
|
Although *users* of this project are only expected to have Visual |
|
Studio 2012 or later, *developers* of the library are required to |
|
have Visual Studio 2015 or later, as the library uses C# 6 features |
|
in its implementation. These features have no impact when using the |
|
compiled code - they're only relevant when building the |
|
`Google.Protobuf` assembly. |
|
|
|
History of C# protobufs |
|
======================= |
|
|
|
This subtree was originally imported from https://github.com/jskeet/protobuf-csharp-port |
|
and represents the latest development version of C# protobufs, that will now be developed |
|
and maintained by Google. All the development will be done in open, under this repository |
|
(https://github.com/google/protobuf). |
|
|
|
The previous project differs from this project in a number of ways: |
|
|
|
- The old code only supported proto2; the new code only supports |
|
proto3 (so no unknown fields, no required/optional distinction, no |
|
extensions) |
|
- The old code was based on immutable message types and builders for |
|
them |
|
- The old code did not support maps or `oneof` |
|
- The old code had its own JSON representation, whereas the new code |
|
uses the standard protobuf JSON representation |
|
- The old code had no notion of the "well-known types" which have |
|
special support in the new code |
|
- The old project supported some older platforms (such as older |
|
versions of Silverlight) which are not currently supported in the |
|
new project
