Microsoft’s C# has received the Tiobe Index Programming Language of the Yr designation for the second time in three years, with the biggest year-over-year improve in rating within the firm’s programming language reputation index. In the meantime, one other Microsoft language, TypeScript, might 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 share factors 12 months over 12 months, with a score of seven.39% and rating of fifth this month. C#’s winning the award had been expected; the language was additionally Tiobe’s language of the year for 2023. “From a language design perspective, C# has usually been an early adopter of recent tendencies amongst mainstream languages,” wrote Paul Jansen, CEO of the software program high quality companies 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 constantly developed on the proper second.” Jansen added that he had anticipated C# to prevail in opposition to 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, stated 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 sorts. “I’ve an extended historical past of constructing incorrect predictions, however I believe that TypeScript will lastly break into the highest 20,” Jansen stated. The language is at the moment ranked thirty second. “The explanation why I believe TypeScript will develop is as a result of I see that numerous front-end software program (consumer interfaces) are written in TypeScript as an alternative of JavaScript these days,” Jansen stated. “The benefit of TypeScript over JavaScript is that it’s type-safe.” If builders use TypeScript in the precise approach, it’s a lot more durable to shoot your self within the foot, Jansen stated. “Adopting TypeScript is with none dangers as a result of TypeScript compiles to JavaScript. Therefore, you may all the time return to JavaScript when you don’t like TypeScript.”
