Summary

The documentation is heavily oriented toward Windows development environments, specifically Visual Studio and .NET Framework. All instructions, examples, and tooling references assume a Windows platform. There are no mentions of Linux or cross-platform alternatives, and all code samples and project setup steps are tailored to Windows users. The use of Visual Studio, .NET Framework (not .NET Core/.NET 5+), and Windows-specific project types further reinforce this bias.

Recommendations

Provide equivalent instructions for Linux and macOS users, including using cross-platform .NET (such as .NET 6/7/8) and editors like VS Code or JetBrains Rider.
Include command-line instructions (e.g., using dotnet CLI) for project creation, package management, and building/running applications.
Clarify which steps are Windows-specific and offer alternatives for other platforms (e.g., running as a .NET Core console app, using cross-platform configuration files).
Mention and demonstrate how to use Azure WCF Relay with .NET Core/.NET 5+ (which is cross-platform) and highlight any limitations or differences.
Add troubleshooting notes for Linux users, especially around WCF support and any required dependencies.
Consider referencing or linking to official Microsoft documentation on running WCF clients/services on non-Windows platforms.
