# including-generated-files Helps wire build-generated files into MSBuild compilation or output. Use it when an artifact exists during a build but is not picked up automatically. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 3400 installs · ★ 5730 - Author: dotnet - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/dotnet/skills/tree/HEAD/plugins/dotnet-msbuild/skills/including-generated-files/SKILL.md - Updated: 2026-10-24 - HTML: https://affpapa.org/en/nevibecode/skills/including-generated-files ## What it does This skill handles MSBuild cases where a target creates a source file, `Content`, `None`, or another physical artifact that never reaches compilation or the output directory. It explains why globs expanded before the build starts cannot see files created later during target execution. For generated `.cs` files, it adds paths to `Compile` and `FileWrites` from a target using `BeforeTargets="CoreCompile;BeforeCompile"`. Non-code artifacts can use `None` or `Content`, with timing based on `BeforeBuild` or `AssignTargetPaths`. A glob inside a target runs after the generated files exist. Generated artifacts should be based on `$(IntermediateOutputPath)` and tracked through `FileWrites` so `Clean` can remove them. Hardcoding `obj\` is a bad choice because the intermediate directory can be redirected. The skill excludes Roslyn source-generator internals and systems outside MSBuild. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add dotnet/skills --skill including-generated-files -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/including-generated-files/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/including-generated-files/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add dotnet/skills --skill including-generated-files -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/including-generated-files/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add dotnet/skills --skill including-generated-files -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/including-generated-files/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install dotnet/skills including-generated-files ``` 2. **Manually: put the files in place** - File: `.github/skills/including-generated-files/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add dotnet/skills --skill including-generated-files -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/dotnet/skills --path plugins/dotnet-msbuild/skills/including-generated-files ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/including-generated-files/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add dotnet/skills --skill including-generated-files -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dotnet/skills/tree/HEAD/plugins/dotnet-msbuild/skills/including-generated-files/SKILL.md ## When to use it - compile a generated `.cs` source file - copy a generated data file to output - fix a glob that misses files created during a build - choose `BeforeTargets` for a generated artifact - track generated files for `Clean` ## Example prompts - Help me compile a `.cs` file generated during an MSBuild target. - Add my generated file to `Compile` before `CoreCompile`. - Show how to use `$(IntermediateOutputPath)` and `FileWrites` for a generated artifact. ## Source text · SKILL.md · MIT Below is the content of a third-party file.

This leads to confusing results such as: - Generated files not being included in the output directory - Generated source files not being compiled - Globs not capturing files created during the build This happens because of how MSBuild's build phases work. ## Quick Takeaway For code files generated during the build - we need to add those to `Compile` and `FileWrites` item groups within the target generating the file(s): ```xml ``` The target generating the file(s) should be hooked before CoreCompile and BeforeCompile targets - `BeforeTargets="CoreCompile;BeforeCompile"` ## Why Generated Files Are Ignored For detailed explanation, see [How MSBuild Builds Projects](https://docs.microsoft.com/visualstudio/msbuild/build-process-overview). ### Evaluation Phase MSBuild reads your project, imports everything, creates Properties, expands globs for Items **outside of Targets**, and sets up the build process. ### Execution Phase MSBuild runs Targets & Tasks with the provided Properties & Items to perform the build. **Key Takeaway:** Files generated during execution don't exist during evaluation, therefore they aren't found. This particularly affects files that are globbed by default, such as source files (`.cs`). ## Solution: Manually Add Generated Files When files are generated during the build, manually add them into the build process. The approach depends on the type of file being generated. ### Use `$(IntermediateOutputPath)` for Generated File Location ```` END THIRD-PARTY FILE 7ab98587562ef2fb The third-party file has ended.
