The dotnet CLI is the command-line interface for working with .NET projects and SDK-based workflows. It can create, build, test, publish, and restore projects, and it uses commands such as dotnet restore and dotnet add package to manage dependencies.
What the dotnet CLI does
The dotnet CLI is the operational interface for SDK-based .NET work: it creates projects, restores dependencies, builds code, runs tests, and publishes outputs. In practice, it is the control surface developers and build systems use to turn source code and package references into compiled, testable, deployable artifacts.
Because it sits at the center of everyday .NET workflow, its value is not just convenience. It standardises project lifecycle actions through a consistent command set, which helps teams automate repeatable build steps and reduce drift between local development and CI pipelines.
Why it matters in software delivery
The CLI matters because it makes .NET projects portable across machines and environments. Commands such as restore and add package express dependencies in a way that can be reproduced by other developers, build agents, and release pipelines. That repeatability is what allows teams to treat the build as a governed process rather than a manual one-off task.
It also shapes how organisations structure developer workflows. When the same interface is used for scaffolding, compilation, testing, and publishing, the CLI becomes the common contract between source control, package sources, and delivery automation. That consistency is especially important when multiple teams need predictable builds from the same repository.
Common commands and workflow boundaries
Most everyday usage falls into a small set of lifecycle steps. Create commands start a project from a template, restore resolves NuGet packages, build compiles the code, test executes automated tests, and publish prepares an application for deployment. The command surface is broad enough to support the full SDK workflow without requiring users to leave the terminal.
Those commands are also boundaries. Restore reaches outside the repository to fetch dependencies, build depends on a correct project file and SDK, test depends on reliable test coverage, and publish depends on the intended runtime and deployment model. Understanding where each step begins and ends helps teams debug failures quickly and keep automation predictable.
Security and supply-chain considerations
Although the dotnet CLI is a developer tool, it touches security-sensitive parts of the delivery chain: package retrieval, build inputs, generated binaries, and the environment in which commands run. A compromised dependency source, a poisoned project file, or an unsafe build context can influence what code gets restored and what gets compiled.
Its command workflow also means that secrets or tokens sometimes appear indirectly in build environments, package feeds, or signing steps. The CLI itself is not a secrets manager, but it often operates in contexts where package credentials, repository access, and release signing material are present. That makes build hygiene and dependency trust central to safe use.
Risk and Threat Considerations
Supply-chain abuse is the main risk around this tool, because the CLI routinely consumes external packages, templates, and repository content. If an attacker can influence what the CLI restores or runs, they can turn a normal build step into a code-execution path or a secret-exposure path.
Failure mechanism: A malicious package, template, script, or manipulated project file can alter the build process, introduce unwanted code, or trigger execution in a developer or CI environment that has broader access than the source itself.
Impact: The result can be credential theft, tampered build artifacts, poisoned releases, or compromise of downstream systems that trust the published output.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
CIS Controls v8, SLSA, OWASP SAMM and NIST SP 800-53 Rev 5 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| CIS Controls v8 | CIS-16 — Application Software Security | The CLI drives software build and dependency workflows that need secure development practices. |
| Recommendation — Require secure build and dependency practices for .NET CLI-based delivery workflows. | ||
| SLSA | Supply-chain Levels for Software Artifacts | The CLI produces and consumes build artifacts whose integrity and provenance matter. |
| Recommendation — Strengthen provenance checks for packages, builds, and published .NET artifacts. | ||
| OWASP SAMM | Software Assurance Maturity Model | The CLI is part of the software delivery process that SAMM helps mature. |
| Recommendation — Use SAMM to mature how teams build, test, and release .NET projects through the CLI. | ||
| NIST SP 800-53 Rev 5 | SA-11 — Developer Testing and Evaluation | CLI-based builds and tests support controlled verification of software before release. |
| CM-8 — System Component Inventory | Dependency restore depends on knowing the components and packages a build consumes. | |
| Recommendation — Use SA-11 to verify .NET builds and tests before releasing CLI-produced artifacts. Inventory build components and dependencies that the .NET CLI restores and compiles. | ||
Practitioner Guidance
What to watch for: Treat the CLI as part of your software supply chain, not just a local developer convenience. Lock down package sources, review restore behavior in CI, and pay attention to any command that fetches or executes content from outside the repository.
Governance implication: Build and release ownership should include dependency policy, provenance checks, and environment hardening, because the CLI sits at the point where source code becomes an artifact.
