Support for .NET 7 Dapr Actors on Apple Silicon (ARM)

Expected Behavior

When building from scratch or upgrading from .NET 6 to .NET 7 packages for dapr (1.9 at the time of writing), I had hoped that the Dapr SDK would continue working. I have a training/demo repository that I have created to learn and play with Dapr components in order to make educated decisions for an upcoming project for work. In this past week, one question that came past my desk was whether to use .NET 7 or .NET 6 for this new project. We understand the risks of not using an LTS version of .NET but we do feel the performance benefits and theoretical simple upgrade path to .NET 8 would be worth it. As such, I played with .NET 7 this week and found issues with our intended use case, specifically around Dapr Actors.

Actual Behavior

However, when I tried updating my ASP.NET 6 Web APIs to .NET 7 with C# 11 and started running into issues. My training repository leverages the following Dapr components:

• Service-to-service invocation
• Secrets management
• State management
• Pub/Sub
• Actors

Of the above, it appeared that only Actors were impacted during the upgrade. Specifically, the issue lay when innovating an Actor’s method through the Actor proxy. Example code of the error I expected can be seen below (link):

public async Task CreateOrderAsync(Order order)
{
  _logger.LogDebug("CreateOrderAsync start. OrderId: {orderId}", order.OrderId);
  var actorId = new ActorId(order.OrderId.ToString());
  var orderActor = ActorProxy.Create<IOrderActor>(actorId, OrderActor.ActorType);
  await orderActor.CreateOrderAsync(order);
  _logger.LogDebug("CreateOrderAsync end. OrderId: {orderId}", order.OrderId);
}

Below is the stack trace of the error:

Dapr.Actors.ActorMethodInvocationException: Remote Actor Method Exception,  DETAILS: Exception: SerializationException, Method Name: ReadObjectHandleExceptions, Line Number: 0, Exception uuid: b26c0996-78f0-4d38-82da-7de0452f1cc8

Steps to Reproduce the Problem

The simplest way to reproduce this error would be

1. Fork my dapr-demo repository
2. Upgrade all projects from .NET 6 to .NET 7
3. Upgrade all projects to use C# 11 instead of C# 10
4. Update all relevant Microsoft NuGet packages from 6.0.x to 7.0.x
5. You can launch the project through the docker-compose.yml and docker-compose.override.yml or just simply setting it as the default launch project in Visual Studio
6. Create an order using the CreateOrderAsync endpoint either through the Swagger UI which is opened upon launch (http://localhost:8000/swagger/index.html) or through the provided Postman collection and environment

Release Note

RELEASE NOTE:

@KrylixZA - Thanks for the detailed info. I’ll see if I can find someone with an M1 Mac to help me reproduce this.
