What's Changed

Validate UseWorkItemFilters names against registered tasks at worker build time by wangbill (@YunchuWang) in #719
Bump Microsoft.Extensions.DependencyInjection.Abstractions to 9.0.1 (fixes azure-functions-durable-extension#3433) by wangbill (@YunchuWang) in #723

Additional notes

Bump DI.Abstractions and Bcl.AsyncInterfaces to 9.0.1 (#3433) (#723)
Validate UseWorkItemFilters names against registered tasks at worker build time (#719)
Bump Microsoft.Extensions.DependencyInjection.Abstractions from 8.0.2 to 9.0.1 (and Microsoft.Bcl.AsyncInterfaces from 8.0.0 to 9.0.1, which the former transitively floors at 9.0.1) to align with the floor declared by Microsoft.Azure.WebJobs 3.0.45 -> Microsoft.Extensions.Logging.Abstractions 9.0.1. Fixes NU1605 in downstream Azure Functions Worker isolated apps consuming Microsoft.DurableTask.Extensions.AzureBlobPayloads (Azure/azure-functions-durable-extension#3433).
Validate explicit UseWorkItemFilters(filters) filter names against the worker's DurableTaskRegistry. Filters that reference an orchestration, activity, or entity name not registered with the worker now throw OptionsValidationException at worker startup instead of silently waiting for work items that will never arrive. No customer-side validation call is required. (#719)
