RKSAD0010

Why this is deprecated

Microsoft.IdentityModel.Clients.ActiveDirectory.UserIdentifierType is part of the Rokstep.IdentityModel.Clients.ActiveDirectory.Shims shim library. The original library is abandoned or deprecated. This diagnostic ID (RKSAD0010) fires at build time to guide you toward the modern replacement.

Obsolete message: Microsoft.IdentityModel.Clients.ActiveDirectory.UserIdentifierType is from the deprecated ADAL library. This Rokstep shim provides structural compatibility. For new code, use MSAL account identifiers directly. See https://dev.rokstep.eu/migrations/RKSAD0010 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.

dotnet add package Rokstep.IdentityModel.Clients.ActiveDirectory.Shims

Option 2 — Migrate to the modern alternative

Replace Microsoft.IdentityModel.Clients.ActiveDirectory.UserIdentifierType with from.
