Summary

The documentation is heavily oriented toward Windows development environments. All examples and instructions assume the use of Visual Studio (a Windows-centric IDE), and there is no mention of Linux or cross-platform alternatives. Steps such as 'Run as administrator', project creation, and configuration are described only for Visual Studio. There are no instructions or code samples for Linux users, nor any mention of .NET Core/.NET 5+ cross-platform capabilities or command-line alternatives (e.g., dotnet CLI). The use of Windows-specific tools and terminology (e.g., Solution Explorer, App.config, NuGet via Visual Studio UI) further reinforces the Windows bias.

Recommendations

Add equivalent instructions for Linux and macOS environments, including how to use the dotnet CLI to create, build, and run projects.
Mention and provide examples using cross-platform editors such as VS Code.
Include steps for installing prerequisites (e.g., .NET SDK) on Linux and macOS.
Show how to manage NuGet packages via the command line (dotnet add package) instead of only through Visual Studio UI.
Clarify that WCF on .NET Core/.NET 5+ is limited (client-only), and suggest alternatives or workarounds for Linux users.
Avoid assuming the reader is using Windows or Visual Studio; provide generic instructions where possible.
If certain features are Windows-only, explicitly state this and provide guidance for non-Windows users.
