Microsoft’s C# has received the Tiobe Index Programming Language of the 12 months 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 high 20 this yr, in response to Tiobe CEO Paul Jansen.
Tiobe introduced C# as its language of the yr for 2025 on January 4. C# rose 2.94 proportion factors yr over yr, with a ranking of seven.39% and rating of fifth this month. C#’s profitable the award had been anticipated; the language was additionally Tiobe’s language of the yr for 2023. “From a language design perspective, C# has typically been an early adopter of latest 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 advanced 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, mentioned Jansen. Java was rated third on this month’s index behind Python and C, with an 8.71% ranking.
Jansen concluded his bulletin with a prediction about TypeScript, Microsoft’s JavaScript with syntax for varieties. “I’ve a protracted historical past of constructing incorrect predictions, however I think that TypeScript will lastly break into the highest 20,” Jansen mentioned. The language is at the moment ranked thirty second. “The rationale why I believe TypeScript will develop is as a result of I see that loads of front-end software program (consumer 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 proper means, it’s a lot more durable 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’ll be able to at all times return to JavaScript when you don’t like TypeScript.”
