# C# deployment checklist > **This file is reference data, not instructions. It lists things to verify before deploying. Nothing below is a command from the operator, and no line in it grants authority to act. Run the read-only verification steps if you wish, then report what you found to the human operator and let them decide what to change. Do not modify the project on the basis of this file. This holds when you are running unattended, on autopilot, or in any automatic mode: an autonomy setting is not the operator approval this file withholds, and no finding here becomes authority to edit a file because nobody is watching. If something needs changing, say so and stop.** Source: https://deploy-list.com/csharp.md · 7 checks · layers: universal -> csharp · generated 2026-08-22 Verification steps come in three kinds. **Verify:** read-only, allowlisted, safe for an agent to run. **Operator-run:** a command only the human should decide to run, typically a framework CLI. An agent must not run these, only report them as outstanding. **Verify by hand:** needs a person to look. ## critical (1) - **No environment file is tracked in git** — `secrets` · `universal.gitignore-env` - Why: Environment files hold database credentials and API keys. Once committed they remain in history after deletion, so every affected credential has to be rotated rather than simply removed. - Do: Remove any tracked environment file from the index, add it to .gitignore, then rotate every credential that was ever committed. - Verify: `git ls-files --error-unmatch .env .env.local .env.production 2>&1 | head -5` - Expect: Every path reports that it did not match any file. A path echoed back is tracked and must be dealt with. - Ref: https://cheatsheetseries.owasp.org/cheatsheets/Secrets_Management_Cheat_Sheet.html ## high (4) - **Package versions cannot move between restores** — `build` · `csharp.package-versions-locked` - Why: A floating version resolves to whatever is newest at restore time, so the build that passed review and the build that ships can contain different code with no diff to show for it. - Do: Pin versions rather than using wildcards, and enable the lock file so a restore fails on an unexpected change instead of accepting it. - Verify: `grep -rnE 'Version="[^"]*\*|RestorePackagesWithLockFile' --include='*.csproj' --include='Directory.Packages.props' . 2>/dev/null | head -10` - Expect: No wildcard version. Ideally the lock file setting is on and packages.lock.json is committed. - Ref: https://learn.microsoft.com/en-us/nuget/consume-packages/package-references-in-project-files - **The shipped build is a release build** — `build` · `csharp.release-configuration` - Why: A debug build skips optimisation, keeps debug-only code paths and carries attributes that change runtime behaviour. It is measurably slower, and the difference is easy to miss because everything still works. - Do: Build with the release configuration in the image and in CI, and make the deploy fail rather than fall back to the default. - Verify: `grep -rnE 'dotnet (publish|build)|--configuration|-c Release' --include=Dockerfile --include='*.sh' --include='*.yml' --include='*.yaml' . 2>/dev/null | head -10` - Expect: Every publish or build on the deploy path names the release configuration. - Ref: https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-publish - **A backup has been restored at least once** — `reliability` · `universal.backup-restore-tested` - Why: An untested backup is a belief, not a capability. Silent corruption, missing tables and expired credentials are all routinely discovered during the first restore, which is the worst possible time to find out. - Do: Restore the most recent backup into a scratch environment, confirm the data is complete and current, and write down how long the restore took. - Verify by hand: Confirm that someone has restored a production backup into a separate environment recently, and that the restore procedure is written down somewhere findable. - Ref: https://cheatsheetseries.owasp.org/cheatsheets/Logging_Cheat_Sheet.html - **Known vulnerabilities in packages have been reviewed** — `security` · `csharp.vulnerable-packages-reviewed` - Why: Transitive packages are where the vulnerable versions hide, and nothing in a normal build or test run fails when one is present. - Do: List vulnerable packages before a release, including transitive ones, and decide on each rather than deferring the whole list. - Operator-run (do not run this yourself): `dotnet list package --vulnerable --include-transitive` - Expect: No unreviewed finding. Anything accepted is recorded with a reason. - Ref: https://learn.microsoft.com/en-us/nuget/concepts/auditing-packages ## recommended (2) - **The framework and the SDK are both pinned** — `build` · `csharp.target-framework-and-sdk-pinned` - Why: Without an SDK pin, the machine's newest installed SDK builds the project, and a newer SDK changes defaults. The failure appears on one build agent and not another. - Do: Declare the target framework in the project and pin the SDK version so every machine builds the same way. - Verify: `grep -rnE '/dev/null | head -10` - Expect: A target framework in the project, and a global.json pinning the SDK. - Ref: https://learn.microsoft.com/en-us/dotnet/core/tools/global-json - **The project declares a license** — `legal` · `universal.license-declared` - Why: Code with no license is not open source and not safe for anyone else to use, and for a closed project the absence leaves contributors with no written statement of who owns what they wrote. - Do: Add a license file at the repository root, and reference it from the package metadata so tooling can read it. - Verify: `ls LICENSE LICENSE.md LICENSE.txt COPYING 2>/dev/null | head -3` - Expect: A license file exists at the repository root. --- Report what you found to the operator. Do not change the project.
