managing-winforms-designer-code

Governs WinForms Designer-generated code structure and InitializeComponent patterns. Use when writing or reviewing .Designer.cs files, fixing "Designer file cannot be loaded" errors, resolving Designer round-trip issues, validating control instantiation in InitializeComponent, implementing proper Dispose(bool disposing) pattern with components.Dispose(), working with IContainer and components field, troubleshooting Designer serialization failures, organizing Designer code vs application logic separation, or understanding what code belongs in InitializeComponent vs elsewhere. Also triggers for "InitializeComponent", ".Designer.cs file", "Designer cannot load", "components.Dispose", "IContainer field", "Designer compatibility", "Designer round-trip", and "Form Designer errors".

# WinForms Designer Code Rules The WinForms Designer generates serialization code, not regular C# code. Understanding and following these rules is CRITICAL for Designer compatibility. **All WinForms Forms and UserControls should be Designer-compatible** — these rules are not optional guidance but mandatory constraints for any code that the Designer must be able to round-trip (read, modify, and re-serialize). ## When to Use This Skill Use this skill when: - Generating the code which makes up a Form or a UserControl in WinForms. - Writing or modifying `.Designer.cs` or `.Designer.vb` files - Creating user controls that need Designer support - Reviewing Designer-generated code - Reviewing whether WinForms Forms/UserControls are "designed according to standard", "not designed properly", or similar; pair this with `managing-winforms-high-dpi-layout` so both Designer serialization and human/layout/DPI quality are checked. - Debugging Designer-related issues - Migrating forms between .NET Framework and .NET - Migrating VB6 Code to either Visual Basic (.NET) or C# WinForms Projects. **IMPORTANT:** Other skills (layout, rendering, data binding, MVVM) describe *what* to build. This skill defines *how* the Designer code-behind file must be structured. When those skills show control configuration, the actual property assignments belong in `InitializeComponent` following the rules below. ## Related Skills - [building-winforms-applications](../building-winforms-applications/SKILL.md) - [managing-winforms-data-binding](../managing-winforms-data-binding/SKILL.md) - [managing-winforms-mvvm](../managing-winforms-mvvm/SKILL.md) - [managing-winforms-high-dpi-layout](../managing-winforms-high-dpi-layout/SKILL.md) - [creating-winforms-custom-controls](../creating-winforms-custom-controls/SKILL.md) ## Detailed Guidance Read [Detailed guide](ref/detailed-guide.md) for comprehensive patterns, examples, and troubleshooting. ## Workflow 1. Confirm the scenario matches the triggers in this skill. 2. Apply the baseline pattern from this file. 3. Read [Detailed guide](ref/detailed-guide.md) for advanced or edge-case handling. 4. Validate changes with an actual build and runtime check.

migrating-inprocess-background-jobs

Ports background jobs from ASP.NET Framework to ASP.NET Core and the .NET Generic Host, and stops a job running twice while the legacy and new hosts are both live. Use when an app uses WebBackgrounder (JobManager, IJob, IJobCoordinator, WebFarmJobCoordinator), HostingEnvironment.QueueBackgroundWorkItem, IRegisteredObject or HostingEnvironment.RegisterObject, timers or Task.Run loops started from Application_Start, WebActivatorEx or OWIN Startup, or console job runners whose Main loops and sleeps or runs once per external trigger. Covers BackgroundService, IHostedService, Channel<T> work queues, Generic Host and Worker Service console jobs, shutdown and failure behaviour, and a duplicate-execution guard for side-by-side migration: a shared SQL schedule row or an Azure blob lease that both hosts take, fencing tokens, and handover. Triggers for "background job", "scheduled job", "hosted service", "job runs twice", "double fire", "leader election", "distributed lock", or "singleton job".

migrating-newtonsoft-to-system-text-json

Migrates .NET projects from Newtonsoft.Json to System.Text.Json, updating package references, code files, and handling API differences. Use when asked to "migrate Newtonsoft", "switch to System.Text.Json", "replace Newtonsoft.Json", or "upgrade JSON library". Triggers for .csproj/.vbproj files referencing Newtonsoft.Json and .cs/.vb files using Newtonsoft.Json namespaces. Also applies when modernizing .NET dependencies or removing third-party JSON libraries.
