```

## Usage

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

const projectFile = path.resolve("Pams/HelperTool/HelperTool.csproj");

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

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

## AI Coding Instructions

- Keep `System.IO.Packaging` declared as a NuGet package reference in `Pams/HelperTool/HelperTool.csproj`.
- Run `dotnet restore` after changing package references before building the HelperTool project.
- Treat this dependency as part of the project’s legacy package-format support.
- Avoid adding JavaScript runtime imports for `System.IO.Packaging`; it is consumed by the .NET HelperTool project.
