DotNetOpenAuth VS cppq

• Comprehensive Support
  DotNetOpenAuth supports multiple OAuth and OpenID versions, making it versatile for different authentication scenarios.
• Security Features
  The library includes built-in features to handle security concerns, such as token encryption and secure transmission protocols.
• Community and Documentation
  DotNetOpenAuth has a history of strong community support and extensive documentation, which can be helpful in learning and troubleshooting.
• Integration with .NET Framework
  The library is designed to integrate seamlessly with the .NET framework, making it easy to implement in existing .NET applications.

Possible disadvantages

• Complexity and Learning Curve
  The library offers many features, which can make it complex and difficult to learn for newcomers.
• Maintenance and Updates
  There have been concerns about the frequency of updates and maintenance, which might affect long-term usability and compatibility with new standards.
• Limited .NET Core Support
  DotNetOpenAuth primarily targets the .NET Framework, with limited support for .NET Core, which may necessitate alternatives for modern applications.
• Performance Overhead
  The extensive feature set can introduce performance overhead, particularly in scenarios that require lightweight solutions.

• Lightweight C++ implementation
  cppq is written in modern C++ and designed to be a minimal, efficient task queue library, making it a good fit for performance-sensitive applications where the overhead of scripting language runtimes is undesirable.
• Redis-backed reliability
  Built on top of Redis as the message broker, cppq benefits from Redis's persistence, atomic operations, and wide adoption, giving the queue system durability and the ability to survive process restarts.
• Inspired by proven design (asynq)
  The library's architecture mirrors the popular Go asynq task queue, so it inherits a well-thought-out API design for task enqueueing, retries, and worker processing patterns that have already been validated in production systems.
• Native integration for C++ projects
  For teams already working in a C++ codebase, cppq allows adding background job processing without needing to introduce a separate service written in another language (like Go or Python), simplifying the technology stack.
• Open source and inspectable
  Being open source on GitHub, developers can review the source code, modify it for custom needs, and contribute improvements, which offers transparency not available with closed-source queueing solutions.

Possible disadvantages

• Limited maturity and battle-testing
  Compared to established task queue libraries like Sidekiq, Celery, or asynq itself, cppq is a newer and smaller project with less real-world production usage, which may translate into undiscovered bugs or edge cases.
• Smaller community and ecosystem
  Because it has far fewer users and contributors than mainstream task queue systems, finding community support, third-party tutorials, or pre-built integrations is more difficult.
• Documentation gaps
  As a smaller project, cppq may have less comprehensive documentation compared to major task queue frameworks, requiring developers to read source code directly to understand advanced features or edge-case behaviors.
• C++ build and dependency complexity
  Using cppq requires managing C++ build toolchains and dependencies (such as a Redis client library), which can be more cumbersome than installing a package via pip or npm in other ecosystems.
• Fewer built-in features and tooling
  cppq likely lacks the extensive ecosystem tooling of more mature queues, such as web-based monitoring dashboards, extensive metrics/observability integrations, or advanced scheduling features found in more established solutions.

• OpenID Provider open source library

  But if the OpenID server would be for a intranet or low number of requests, you can go ahread (in my opinion) and the post also recommends http://dotnetopenauth.net/ because has a OpenID provider and samples. Source: about 4 years ago
