Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Legacy ASP.NET
Trigger On
- working in Web Forms, legacy MVC, or classic ASP.NET applications
- reviewing old IIS-centric configuration and lifecycle behavior
- planning migration toward ASP.NET Core without breaking core business flows
Workflow
- Treat classic ASP.NET as a distinct stack with different hosting, lifecycle, and configuration rules from ASP.NET Core.
- Stabilize behavior first: routing, session, auth, server controls, configuration transforms, and deployment assumptions.
- Plan modernization in seams: isolate domain and service logic, then move replaceable edges instead of rewriting the whole app at once.
- Use
dotnet-wcfordotnet-entity-framework6when the legacy app depends on those subsystems rather than flattening them into generic web work. - Be careful with guidance copied from ASP.NET Core because middleware, DI, and hosting assumptions do not transfer directly.
- Validate in an environment that resembles real IIS and configuration transforms.
Deliver
- practical maintenance guidance for classic ASP.NET
- stabilized legacy behavior and modernization seams
- a migration path that avoids unnecessary risk
Validate
- classic and Core guidance are not mixed
- legacy runtime assumptions are preserved deliberately
- migration steps are incremental and testable
