What's Changed

High level

  • mpc tool is gone. We use roslyn source generators now.
  • Source generation is enabled by default. At runtime MessagePack v3 will look for these source generated formatters and avoid generating them dynamically if found.

See our migration guide.
Details blog article

What's new

  • AOT source generation of formatters by default using roslyn source generators. mpc is no longer available. Dynamic formatters still exist (for runtimes that support them), but code that compiles against v3 are unlikely to need them, resulting in better startup performance and improved debugging experience.
  • AOT source generation is hugely improved.
    • Support most or all of the data types that DynamicObjectResolver supported.
    • Support for serializing private members.
  • [MessagePackObject] types can serialize private members without the application having to switch to DynamicObjectResolverAllowPrivate.
  • Analyzers are on by default, with many new ones to help ensure your code is correct and ready for AOT source generated formatters.
  • Custom formatters are automatically used for the data types they format when defined in the same assembly, by default. No need to attribute your data types to point to the custom formatter. Opt out by attributing the formatter with [ExcludeFormatterFromSourceGeneratedResolverAttribute].
  • New CompositeResolverAttribute offers a faster runtime alternative to the CompositeResolver class.

Unity

  • Consume through NuGetForUnity and UPM instead of through .unitypackage
