Versioning issues with AgentNet.InProcess.Polly rc.5

[JordanMarr]

Need to verify versions in Polly rc.5 package.

Could not make an assembly reference to AgentNet.Interop, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.DurableTask.Abstractions, Version=1.22.0.0, Culture=neutral, PublicKeyToken=6a4c0315c2d1d937'. The system cannot find the file specified.

Hey Onur, thanks for the error details.

The root cause isn't the .props refactor — the published nupkg metadata is actually correct. The real issue is that AgentNet.Interop.dll is bundled into every package (including AgentNet.InProcess), and it contains types that reference Microsoft.DurableTask.Abstractions. Since AgentNet.InProcess doesn't declare that as a dependency, the assembly fails to load at runtime when those types are accessed.

I'm working on a fix now — will update when it's ready.

Hey @OnurGumus

I dug into the packaging behavior and found the underlying cause:
the old AgentNet.Interop project was bundling DurableTask‑dependent types into the InProcess package, which meant consumers could hit missing‑assembly errors even when they weren’t using Durable execution.

I’ve split the interop layer into three small, focused projects (Workflow.Abstractions, InProcess.Interop, and Durable.Interop) and updated the packaging so each runtime only ships the assemblies it actually needs. This keeps the dependency boundaries clean and avoids the cross‑runtime leakage that triggered the original problem.

The fix is published as 1.0.0‑rc.6, and I’ve verified it against the published packages — including the test that ensures AgentNet.InProcess.Interop.dll loads cleanly with no DurableTask dependency.

Thanks again for surfacing this. Let me know if you run into anything else.
