RKSEL0009
Why this is deprecated
Elmah.ErrorMail is part of the Rokstep.Elmah.Shims shim library. The original library is abandoned or deprecated. This diagnostic ID (RKSEL0009) fires at build time to guide you toward the modern replacement.
Obsolete message: Elmah.ErrorMail.Send is the synchronous wrapper kept for ELMAH 1.2.2 compatibility. Prefer SendAsync to avoid sync-over-async thread-pool starvation. See https://dev.rokstep.eu/migrations/RKSEL0009 for migration guidance.

Install the shim package and keep using the existing API. The shim compiles your code but emits this warning at build time.
