Pull request overview
This PR aims to restore Azure Functions in-proc host (net8.0) compatibility by pinning shared-framework dependencies back to 8.x so the extension assemblies don’t require Microsoft.Extensions.* (and related) 10.x assembly versions that the host cannot load.
Changes:
- Adds an IMPORTANT note in
Directory.Packages.propsexplaining the Azure Functions host shared-framework constraint. - Reverts several centrally-managed shared-framework package versions (e.g.,
System.Text.Json,Microsoft.Bcl.AsyncInterfaces, variousMicrosoft.Extensions.*) back to 8.x.

…compatibility The Azure Functions host process runs on net8.0 and loads DurableTask extension assemblies into its process. Packages like Microsoft.Extensions.*, Bcl.AsyncInterfaces, and System.Text.Json are part of the .NET shared framework - the host only provides version 8.0.0.0 of these assemblies. PR #510 upgraded these to 10.x, which causes FileNotFoundException at runtime: Could not load file or assembly 'Microsoft.Extensions.Options, Version=10.0.0.0' This reverts the 11 shared-framework packages to 8.x while keeping all other dependency upgrades (Grpc, Protobuf, Azure.Storage.Blobs, Azure.Identity, etc). Packages reverted: - Microsoft.Extensions.* (9 packages): 10.0.2 -> 8.x - Microsoft.Bcl.AsyncInterfaces: 10.0.2 -> 8.0.0 - System.Text.Json: 10.0.2 -> 8.0.5 Test project fix: - Generators.Tests: VersionOverride for DependencyInjection (net10 test project needs 10.x via Functions.Worker transitive dep, safe since tests don't load into the Functions host) global.json: relaxed SDK version to match installed 10.0.104

Problem
The Azure Functions host process runs on net8.0 (source) and loads DurableTask extension assemblies into its process. Packages like
Microsoft.Extensions.*,Microsoft.Bcl.AsyncInterfaces, andSystem.Text.Jsonare part of the .NET shared framework — the host only provides version8.0.0.0of these assemblies.PR #510 upgraded these to 10.x, causing
FileNotFoundExceptionat runtime when used as a Functions host extension:\
Could not load file or assembly 'Microsoft.Extensions.Options, Version=10.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.
\\
Azure Functions 'supports .NET 10' only in the isolated worker process — the host process remains net8.
Fix
Revert 11 shared-framework packages to 8.x while keeping all other upgrades (Grpc, Protobuf, Azure.Storage.Blobs, Azure.Identity, CodeAnalysis, test frameworks):
Microsoft.Extensions.Caching.MemoryMicrosoft.Extensions.Configuration.AbstractionsMicrosoft.Extensions.DependencyInjectionMicrosoft.Extensions.DependencyInjection.AbstractionsMicrosoft.Extensions.HostingMicrosoft.Extensions.Hosting.AbstractionsMicrosoft.Extensions.Logging.AbstractionsMicrosoft.Extensions.OptionsMicrosoft.Extensions.Options.DataAnnotationsMicrosoft.Bcl.AsyncInterfacesSystem.Text.JsonAdded
IMPORTANTcomment inDirectory.Packages.propsexplaining why these must stay at 8.x.Test fix
Generators.Tests.csproj(net10 test project) getsVersionOverride=\"10.0.2\"forMicrosoft.Extensions.DependencyInjectionsinceMicrosoft.Azure.Functions.Worker 2.51.0transitively needs 10.x. This is safe — test projects don't load into the Functions host.t this change also adds a VersionOverride for Microsoft.Extensions.Hosting
