The post discusses the advantages and challenges of using C# as a programming language, particularly in the context of the SaaS security product Tracebit. Key points include the stability of the .NET ecosystem, the ease of managing dependencies and version migrations, and the built-in features that come with C#. While many developers appreciate C# for its versatility and the strong tooling provided by the .NET framework, there are concerns about its growing complexity and the rapid evolution of the language leading to potential legacy code issues. It highlights that while C# achieves high performance across various applications, developers may find it hard to maintain older code due to new language features and competing frameworks. Despite these challenges, C# remains a favored choice for long-term projects in the B2B space, eclipsing newer languages due to its strong foundational capabilities and stability in library support.
