Orleans now ignores failed probes triggered by long GC pauses, a fix that could save your cluster from false member faults.

Orleans shipped a resilience fix that suppresses faults when an inter-silo probe times out due to a long GC pause, with the default threshold set to 25% of the window, meaning a pause of at least 1.25 seconds will be ignored [1]. This pairs with new grain placement resilience policies [2] and stricter split handoff invariant tests [3], all from ReubenBond, tightening the core of Orleans' fault tolerance. Meanwhile, a new file-based grain storage provider `Orleans.Persistence.FileStorage` is landing [4], and Event Hubs streaming gets Aspire support, though it's still draft pending Aspire's non-connection-string property support [5]. Over on dotnet/dotnet and dotnet/runtime, the day is mostly routine codeflow and dependency bumps: aspnetcore and runtime updates [6][7], roslyn [8][9], and ICU and xharness [10][11]. Notably, runtime is removing dead net8 code since `NetCoreAppMinimum` is now net10, a clear signal that net8 is being pruned from the main branch [12]. The dependency churn is low-risk, but the Orleans changes are worth a close look before your next cluster deploy.
