Microsoft’s C# has gained 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 recognition index. In the meantime, one other Microsoft language, TypeScript, might crack the index’s prime 20 this yr, in line with Tiobe CEO Paul Jansen.
Tiobe introduced C# as its language of the yr for 2025 on January 4. C# rose 2.94 share 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 usually been an early adopter of latest 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 similar 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 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 type 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% 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 believe that TypeScript will lastly break into the highest 20,” Jansen stated. 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 a variety of front-end software program (consumer interfaces) are written in TypeScript as a substitute of JavaScript these days,” Jansen stated. “The benefit of TypeScript over JavaScript is that it’s type-safe.” If builders use TypeScript in the correct approach, it’s a lot tougher 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 possibly can all the time return to JavaScript in the event you don’t like TypeScript.”
