A Roslyn analyzer for C# that enforces good practices in design, usage, security, performance, and style.
Meziantou.Analyzer is a Roslyn-based static code analyzer for C# that enforces good coding practices across design, usage, security, performance, and style. It helps developers identify and fix common issues in their codebase automatically, improving overall code quality and maintainability.
C# developers and teams looking to enforce consistent coding standards, improve performance, and enhance security in their .NET projects through automated static analysis.
It provides a comprehensive set of over 190 rules with automatic code fixes, covering areas often missed by default analyzers, and integrates seamlessly into the Visual Studio IDE and CI/CD pipelines.
A powerful C# Roslyn analyzer that uses static analysis to detect bugs, surface security issues, and enforce best practices—helping developers and AI write more reliable code.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Includes over 190 rules across design, performance, security, usage, and style, such as MA0005 for using Array.Empty<T>() and MA0009 for regex timeouts, ensuring broad code quality improvements.
Many rules provide automatic code fixes, like MA0004 for Task.ConfigureAwait and MA0020 for optimizing LINQ methods, reducing manual refactoring effort during development.
Installs via NuGet and works within Visual Studio, offering real-time feedback and fixes without external tools, as shown in the installation and rule enforcement details.
Targets real-world vulnerabilities with rules like MA0039 against custom certificate validation and MA0009 for regex timeouts, enhancing application security directly.
Several rules lack automatic code fixes, such as MA0012 for reserved exceptions and MA0039 for certificate validation, forcing manual corrections and increasing maintenance overhead.
The README admits duplication with other analyzers, which can lead to redundant warnings and complicate configuration, especially in projects already using tools like StyleCop or FxCop.
Adding numerous analyzers may increase compilation times, particularly in large projects, impacting developer productivity without easy opt-outs for specific rules.
