Assessing Breaking ChangesGuides assessment of backward compatibility for MSBuild changes. Consult when modifying behavior, adding warnings or errors, changing defaults, altering target ordering, removing or deprecating features, deciding whether a change needs a ChangeWave, reviewing blast radius of behavioral changes, or when a PR introduces user-visible output differences.Authoring Errors And WarningsGuides authoring of MSBuild errors, warnings, and diagnostic messages. Consult when adding new MSBxxxx codes, writing or modifying user-facing diagnostic text, deciding between error/warning/message severity, working with Strings.resx resource files, formatting paths in error output, or evaluating whether a new warning could break WarnAsError builds.Binlog AnalysisTriage a build / compile / restore / WarnAsError failure from its MSBuild binary log. Fetches the binlog (a local build's, or a failed dotnet/fsharp Azure DevOps PR build's published artifact) and analyzes it live via the `binlog-mcp` MCP server — structured errors, root-cause diagnosis, and an MSBuild perf X-ray. NOT for test failures or CheckCodeFormatting: a build binlog has no errors there.Change TrackingImplementation details for EF Core change tracking. Use when changing InternalEntityEntry, ChangeDetector, SnapshotFactoryFactory, or related entity state, snapshot, or property accessor code.ChangewavesManage MSBuild Change Waves: create new waves, condition features behind opt-out flags, write tests for wave-gated features, document change waves in ChangeWaves.md, and retire expired waves. Use when adding changes that need an opt-out or rotating out old change waves. Changes that introduce a user-visible behavior change should consider whether to use a changewave.Cosmos ProviderImplementation details for the EF Core Azure Cosmos DB provider. Use when changing Cosmos-specific code.
