Microsoft’s C# has received the Tiobe Index Programming Language of the 12 months designation for the second time in three years, with the most important year-over-year enhance in rating within the firm’s programming language reputation index. In the meantime, one other Microsoft language, TypeScript, could crack the index’s prime 20 this 12 months, based on Tiobe CEO Paul Jansen.
Tiobe introduced C# as its language of the 12 months for 2025 on January 4. C# rose 2.94 proportion factors 12 months over 12 months, with a score of seven.39% and rating of fifth this month. C#’s successful the award had been anticipated; the language was additionally Tiobe’s language of the 12 months for 2023. “From a language design perspective, C# has typically been an early adopter of recent traits amongst mainstream languages,” wrote Paul Jansen, CEO of the software program high quality providers vendor, in a bulletin accompanying the January 2026 index. “On the identical time, it efficiently made two main paradigm shifts: from Home windows-only to cross-platform, and from Microsoft-owned to open supply. C# has persistently developed on the proper second.” Jansen added that he had anticipated C# to prevail towards Java for dominance within the enterprise software program market, however the contest at this level stays undecided. “It’s an open query whether or not Java—with its verbose, boilerplate-heavy model and Oracle possession—can proceed to maintain C# at bay, mentioned Jansen. Java was rated third on this month’s index behind Python and C, with an 8.71% score.
Jansen concluded his bulletin with a prediction about TypeScript, Microsoft’s JavaScript with syntax for varieties. “I’ve an extended historical past of creating incorrect predictions, however I believe that TypeScript will lastly break into the highest 20,” Jansen mentioned. The language is at present ranked thirty second. “The rationale why I believe TypeScript will develop is as a result of I see that plenty of front-end software program (person interfaces) are written in TypeScript as an alternative of JavaScript these days,” Jansen mentioned. “The benefit of TypeScript over JavaScript is that it’s type-safe.” If builders use TypeScript in the correct method, it’s a lot tougher to shoot your self within the foot, Jansen mentioned. “Adopting TypeScript is with none dangers as a result of TypeScript compiles to JavaScript. Therefore, you possibly can at all times return to JavaScript in case you don’t like TypeScript.”
