```

## Usage

```ts
import { execFileSync } from "node:child_process";

const projectFile = "Pams/HelperTool/HelperTool.csproj";

execFileSync("dotnet", ["restore", projectFile], {
  stdio: "inherit",
});

execFileSync("dotnet", ["build", projectFile], {
  stdio: "inherit",
});
```

## AI Coding Instructions

- Keep the `System.Deployment` package reference in `HelperTool.csproj`; restore the project after changing package metadata.
- Check the package version already declared in the project file before updating it.
- Use `dotnet restore` before builds in local scripts and CI environments.
- Treat this as a legacy-format NuGet dependency and avoid changing project format unless related build configuration is updated.
