Build, maintain, or modernize Windows Forms applications with practical guidance on designer-driven UI, event handling, data binding, MVP separation, and migration to modern .NET. Use when working on WinForms projects or migrating from .NET Framework.

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

# Windows Forms

## Trigger On

- working on Windows Forms UI, event-driven workflows, or classic LOB applications
- migrating WinForms from .NET Framework to modern .NET
- cleaning up oversized form code or designer coupling
- implementing data binding, validation, or control customization

## Workflow

1. **Respect designer boundaries** — never edit `.Designer.cs` directly; changes are lost on regeneration.
2. **Separate business logic from forms** — use MVP (Model-View-Presenter) pattern. Forms orchestrate UI; presenters contain logic; services handle data access.
   ```csharp
   // View interface — forms implement this
   public interface ICustomerView
   {
       string CustomerName { get; set; }
       event EventHandler SaveRequested;
       void ShowError(string message);
   }

   // Presenter — testable without UI
   public class CustomerPresenter
   {
       private readonly ICustomerView _view;
       private readonly ICustomerService _service;
       public CustomerPresenter(ICustomerView view, ICustomerService service)
       {
           _view = view;
           _service = service;
           _view.SaveRequested += async (s, e) =>
           {

How to install

The exact contents, by fingerprint

mdr add postpartum-genushyacinthus29/dotnet-skills/dotnet-winforms@sha256:54bfdfbc3e6aaf88

The line at the top of this page pins the label v1.0.1, 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.
