dotnet-legacy-aspnet from postpartum-genushyacinthus29/dotnet-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add postpartum-genushyacinthus29/dotnet-skills/dotnet-legacy-aspnet@v1.0.0

Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Maintain classic ASP.NET applications on .NET Framework, including Web Forms, older MVC, and legacy hosting patterns, while planning realistic modernization boundaries.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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

1. Treat classic ASP.NET as a distinct stack with different hosting, lifecycle, and configuration rules from ASP.NET Core.
2. Stabilize behavior first: routing, session, auth, server controls, configuration transforms, and deployment assumptions.
3. Plan modernization in seams: isolate domain and service logic, then move replaceable edges instead of rewriting the whole app at once.
4. Use `dotnet-wcf` or `dotnet-entity-framework6` when the legacy app depends on those subsystems rather than flattening them into generic web work.
5. Be careful with guidance copied from ASP.NET Core because middleware, DI, and hosting assumptions do not transfer directly.
6. 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

How to install

The exact contents, by fingerprint

mdr add postpartum-genushyacinthus29/dotnet-skills/dotnet-legacy-aspnet@sha256:d19cc135ce3180fe

The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
