Upgrading IdentityServer v7 to v8

When to Use This Skill

  • Upgrading a Duende IdentityServer project from v7.4 to v8.0
  • Fixing build errors after updating NuGet packages to v8
  • Migrating custom stores/services to new v8 interfaces
  • Running EF Core database migrations for v8 (SAML tables)
  • Replacing deprecated APIs (ICache, IClock, IAuthorizationParametersMessageStore)

Core Principles

  • v8.0 requires .NET 10 — update TFM before anything else
  • All breaking changes are compile-time errors (no silent behavior changes)
