I got the following error when compiling client-side of StreamingHubClient sample (.net 8.0)
Error CS0234 The type or namespace name 'MagicOnion' does not exist in the namespace 'MessagePack.Formatters' (are you missing an assembly reference?)

• I checked all packages in project, what is missing?

  PackageReference Include="MagicOnion.Abstractions" Version="6.1.3"
  PackageReference Include="MagicOnion.Client" Version="6.1.3"
  PackageReference Include="MagicOnion.Serialization.MessagePack" Version="6.1.3"
  PackageReference Include="MagicOnion.Shared" Version="6.1.3"

What source code does the error occur in? In the code you wrote or in the code generated by the Source Generator?

looks like it is in code generated by source generator,
the error is in file
MOClient_MagicOnionGeneratedClientInitializer_MessagePack.g.cs

[mayuki]

so Message Pack Compiler may kick in?

Message Pack packages that I have installed:
