powershell_heavy

windows_tools
Summary:
The documentation provides a balanced set of code samples for generating SAS tokens in multiple languages (NodeJS, Java, PHP, C#, PowerShell, Bash). However, there is a mild Windows bias: PowerShell (a Windows-centric tool) is given a dedicated section, and the Bash example (for Linux/macOS) is placed last. Additionally, disabling SAS authentication is only described via the Azure Portal (a GUI tool most accessible on Windows) and ARM templates, with no mention of CLI or Linux-native tooling. There are no explicit Linux command-line (Azure CLI) examples for management tasks, and the documentation references .NET samples first in the 'Samples' section.
Recommendations:
- Reorder code samples so that Bash (Linux/macOS) appears before PowerShell, or present them side-by-side.
- Add Azure CLI examples for management tasks such as disabling SAS/local authentication, alongside ARM template and Portal instructions.
- Include references to SDK samples in other languages (e.g., Python, Java) and not just .NET, to improve cross-platform parity.
- Explicitly mention that Bash scripts are suitable for Linux/macOS environments, and PowerShell for Windows, to guide users.
- Where possible, provide parity in tooling instructions (e.g., show how to perform management tasks using both Azure CLI and Portal).
