@StephenMolloy This needs to target the release/8.0-staging branch, not the release/8.0 branch directly. Can you please make the change? Make sure the branch switch doesn't accidentally bring in unrelated commits. |

Because this change affects an OOB package: You'll also have to follow these instructions to enable building the package: https://github.com/dotnet/runtime/blob/main/docs/project/library-servicing.md#check-if-a-package-is-generated OOB assemblies don't get built by default in servicing branches. |

Timer was updated in 5.0 to improve performance, but is prone to deadlocks when manipulated in an unhandled exception handler. Which MemoryCache does. And MemoryCache is probably more likely to witness unhandled exceptions like OOM than typical code.
Original Issue: #64115 (and #102666)
.Net 9.0 PR: #103937
System.Runtime.Caching is an OOB package that ships alongside the runtime.
