managing-winforms-data-binding

Implements WinForms data binding patterns with BindingSource, INotifyPropertyChanged, validation, and master-detail scenarios. Use when binding controls using DataBindings.Add, setting up BindingSource with DataSource, implementing INotifyPropertyChanged for automatic UI updates, creating two-way bindings between controls and data objects, using BindingSource.Filter or BindingSource.Sort, implementing master-detail relationships with related BindingSources, handling binding validation with ErrorProvider, or troubleshooting binding update issues and performance. Also triggers for "BindingSource", "DataBindings.Add", "INotifyPropertyChanged WinForms", "two-way binding", "ErrorProvider", "master-detail binding", "BindingNavigator", "DataSource binding", and "WinForms data binding".

migrating-csharp-nullable-references

Enable nullable reference types in a C# project and systematically resolve all warnings. Use when adopting NRTs in existing codebases, performing file-by-file or project-wide nullable migration, fixing CS8602/CS8618/CS86xx warnings, annotating APIs for nullability, cleaning up null-forgiving operators, or upgrading dependencies with new nullable annotations. Also use when the user asks to "enable nullable", "turn on NRTs", "annotate for nullability", "fix nullable warnings", or "migrate to nullable reference types". DO NOT USE FOR: projects already fully migrated with zero warnings (unless auditing suppressions), fixing a handful of nullable warnings in code that already has NRTs enabled, suppressing warnings without fixing them, C# 7.3 or earlier projects. INVOKES: Get-NullableReadiness.ps1 scanner script.

managing-shared-database-schema

Governs a SQL database that two hosts read and write at the same time during a side-by-side migration. Use when a legacy .NET Framework app and a new .NET app share one database, point at the same connection string, or must both stay live while the schema changes. Covers which toolchain owns schema changes, expand-then-contract (additive-only) evolution, dual-write and backfill ordering, deployment ordering, and rollback rules. Triggers for "shared database", "who runs migrations", "dual write", "zero downtime schema change", or "add a column safely". Applies to EF6, EF Core, Dapper, ADO.NET, DACPAC/SqlPackage, DbUp and Flyway, and explains how EF6's __MigrationHistory and EF Core's __EFMigrationsHistory coexist without merging. Also use before deleting a Migrations folder, before enabling Database.Migrate() at startup, or when asked whether renaming or dropping a column is safe while the old app is live.

migrating-edmx-to-code-first

Migrates Entity Framework 6 EDMX-based models (Database-First/Model-First) to EF Core Code-First. Use when upgrading projects containing .edmx files, .Context.tt templates, EntityClient connection strings, or ObjectContext references. Triggers for "migrate EDMX", "convert EDMX to code first", "EF6 to EF Core", "remove EDMX", "database first to code first", and "scaffold DbContext". Also relevant when encountering EntitySQL, EntityObject, or ObjectSet patterns during .NET modernization.
