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 improve in rating within the firm’s programming language reputation index. In the meantime, one other Microsoft language, TypeScript, could crack the index’s high 20 this yr, in keeping with 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 successful 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 developments 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 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% ranking.
Jansen concluded his bulletin with a prediction about TypeScript, Microsoft’s JavaScript with syntax for varieties. “I’ve a protracted historical past of creating incorrect predictions, however I believe that TypeScript will lastly break into the highest 20,” Jansen stated. The language is at present ranked thirty second. “The explanation why I believe TypeScript will develop is as a result of I see that a number of front-end software program (person 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 correct method, 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 may all the time return to JavaScript in the event you don’t like TypeScript.”
