Highlights

MagicOnion.Client.SourceGenerator in #688

This release introduces a source generator for platform that require pre-generated client code (e.g. Unity, NativeAOT, MAUI ...).
The source generator also replaces MagicOnion.Generator (moc).

MagicOnion.Client.SourceGenerator is shipped with MagicOnion.Client package. This means that you no longer need to the install generator tool (moc) and setup additional build steps.

Supported development environments

• Unity 2021.3.0f1 or later
• .NET 6 or later
• Visual Studio 2022 version 17.2 or later
• Rider 2023.1 or later

Usage

Define a partial class with any name of your choosing within the application. Mark it with the MagicOnionClientGeneration attribute, and specify any service type found within the assembly where you want to search for the service interface.

For example, if the MyApp.Shared assembly contains MyApp.Shared.Services.IGreeterService and MyApp.Shared.Hubs.IChatHub, specify one of them.

using MagicOnion.Client;

[MagicOnionClientGeneration(typeof(MyApp.Shared.Services.IGreeterService))]
partial class MagicOnionGeneratedClientInitializer {}

Next, configure MessagePack to use the generated MessagePack Resolver. This is the same as when using the legacy MagicOnion.Generator.

#if UNITY_2019_4_OR_NEWER
[UnityEngine.RuntimeInitializeOnLoadMethod(UnityEngine.RuntimeInitializeLoadType.BeforeSceneLoad)]
#elif NET5_0_OR_GREATER
[System.Runtime.CompilerServices.ModuleInitializer]
#endif
static void RegisterResolvers()
{
    StaticCompositeResolver.Instance.Register(
        // Add: Use MessagePack formatter resolver generated by the source generator.
        MagicOnionGeneratedClientInitializer.Resolver,
        MessagePack.Resolvers.GeneratedResolver.Instance,
        BuiltinResolver.Instance,
        PrimitiveObjectResolver.Instance
    );

    MessagePackSerializer.DefaultOptions = MessagePackSerializer.DefaultOptions
        .WithResolver(StaticCompositeResolver.Instance);
}

Source generation options

You can specify options in the named constructor of the attribute.

• DisableAutoRegistration: Sets whether to disable automatically calling Register during start-up. (Automatic registration requires .NET 5+ or Unity)
• MessagePackFormatterNamespace: Sets the namespace of pre-generated MessagePackFormatters. The default value is MessagePack.Formatters.
• Serializer: Sets the serializer used for message serialization. The default value is GenerateSerializerType.MessagePack.

Breaking changes

MagicOnion.Generator (moc) has been removed. The legacy generator is no longer supported.

Warning

While there is currently compatibility between MagicOnion.Client and MagicOnion.Generator (moc), there is no guarantee that this will be maintained.

Introduce ServiceContext.SetRawBytesResponse in #677

This PR introduces ServiceContext.SetRawBytesResponse method.

This method allows you to set raw byte sequences as a response. This makes it possible to send a cached response body without serialization.

public override async ValueTask Invoke(ServiceContext context, Func<ServiceContext, ValueTask> next)
{
    if (ResponseBytesCache.TryGetValue(context.CallContext.Method, out var cachedBytes))
    {
        context.SetRawBytesResponse(cachedBytes);
        return;
    }

    await next(context);

    ResponseBytesCache[context.CallContext.Method] = MessagePackSerializer.Serialize(context.Result);
}

Note

The raw byte sequence must be serialized as a MessagePack (or custom serialization) format. MagicOnion will write a byte requence directly into the response buffer.

Add StreamingHub metrics in #716

This release introduces metrics related to StreamingHub using System.Diagnostics.Metrics.

• see: https://learn.microsoft.com/en-us/dotnet/core/diagnostics/metrics

Meter: MagicOnion.Server

Metric	Unit	Tags
magiconion.server.streaminghub.connections	{connection}	rpc.system, rpc.service
magiconion.server.streaminghub.method_duration	ms	rpc.system, rpc.service, rpc.method
magiconion.server.streaminghub.method_completed	{request}	rpc.system, rpc.service, rpc.method, magiconion.streaminghub.is_error
magiconion.server.streaminghub.exceptions	{exception}	rpc.system, rpc.service, rpc.method, error.type

Tags

Tag name	Value
rpc.system	magiconion
rpc.service	StreamingHub interface name (e.g. IGreeterService)
rpc.method	StreamingHub method name (e.g. HelloAsync)
magiconion.streaminghub.is_error	Whether a StreamingHub method call succeeded or failed. (e.g. true or false)
error.type	Thrown exception type (e.g. System.InvalidOperationException)

Breaking Changes

Use Grpc.Net.Client by default on Unity in #704

This release changes the default gRPC library in Unity to grpc-dotnet.
From this release, the recommended gRPC library combination is YetAnotherHttpHandler and grpc-dotnet.

However, at this time, we are still supporting C-core. If you continue to use the C-core gRPC library, please define USE_GRPC_CCORE in "Scripting Define Symbols". We recommend transitioning as there is the possibility of removing support in the future.
