Summary

The documentation demonstrates a Windows bias in several ways: Windows is explicitly referenced as the development environment in multiple places, with instructions such as 'Open a Windows command prompt' and references to Windows-based machines. While some steps mention that they work on both Windows and Linux, the article consistently uses Windows as the example environment, and Linux-specific instructions or clarifications are missing or minimal. Some tooling and scripting examples (such as using Git Bash or sed) are presented, but the overall flow and sample commands are Windows-centric, and Linux users are left to infer how to adapt steps. There are also references to Windows tools and patterns (e.g., registry for secrets, Windows command prompt), and Linux equivalents are not given or are only mentioned as an afterthought.

Recommendations

Provide explicit Linux and macOS instructions and command-line examples alongside Windows ones, especially for steps like creating projects, running commands, and editing files.
Avoid phrases like 'Open a Windows command prompt'—instead, use neutral language such as 'Open a terminal' and specify differences in sub-sections if needed.
When referencing tools (e.g., storing secrets in the registry), mention Linux/macOS equivalents (such as environment variables or configuration files).
Ensure that all code and command-line snippets are provided in both Windows (cmd/PowerShell) and Linux/macOS (bash/sh) formats where syntax differs.
For certificate creation and manipulation, provide clear instructions for both Windows and Linux users, including any OS-specific prerequisites or tool usage.
Where screenshots or UI steps are shown, clarify any OS-specific differences or note that the portal experience is OS-agnostic.
Review all references to 'Windows-based machine' and replace with 'development machine' or similar neutral terms, specifying OS only where necessary.

    private static string ProvisioningConnectionString = "{ProvisioningServiceConnectionString}";
    private static string EnrollmentGroupId = "enrollmentgrouptest";
    private static string X509RootCertPath = @"{Path to a .cer or .pem file for a verified root CA or intermediate CA X.509 certificate}";

    Copy and paste the output certificate text for the constant value.

    > [!IMPORTANT]
    > In production code, be aware of the following security considerations:
    >
    > * Hard-coding the connection string for the provisioning service administrator is against security best practices. Instead, the connection string should be held in a secure manner, such as in a secure configuration file or in the registry.
    > * Be sure to upload only the public part of the signing certificate. Never upload .pfx (PKCS12) or .pem files containing private keys to the provisioning service.

1. The sample allows you to set an IoT hub in the enrollment group to provision the device to. This must be an IoT hub that was previously linked to the provisioning service. For this article, we let DPS choose from the linked hubs according to the default allocation policy, evenly weighted distribution. Comment out the following statement in the file:

2. Upon successful creation, the command window displays the properties of the new enrollment group.

:::zone-end

:::zone pivot="programming-language-nodejs"

1. Run the following command in your command prompt. Include the quotes around the command arguments and replace `<connection string>` with connection string you copied in the previous section, and `<certificate .pem file>` with the path to your certificate `.pem` file. This file represents the public part of a either a root CA X.509 certificate that was previously uploaded and verified with your provisioning service, or an intermediate certificate that was uploaded and verified or had a certificate in its signing chain uploaded and verified.
