RKSEL0001

Why this is deprecated

Elmah.Error is part of the Rokstep.Elmah.Shims shim library. The original library is abandoned or deprecated. This diagnostic ID (RKSEL0001) fires at build time to guide you toward the modern replacement.

Obsolete message: Elmah.Error is from the deprecated ELMAH library. This Rokstep.Elmah.Shims keeps your existing code working on .NET 6/8. For new code, use Microsoft.Extensions.Logging with structured logging and an error-tracking sink such as Sentry, Application Insights, or OpenTelemetry. See https://dev.rokstep.eu/migrations/RKSEL0001 for migration guidance.

What you can do

Option 1 — Drop-in shim (zero code changes)

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

Terminal window
dotnet add package Rokstep.Elmah.Shims

Option 2 — Migrate to the modern alternative

Replace Elmah.Error with from.
