C#, Microsoft’s object-oriented, cross-platform, open source language for the .NET platform, has become the fastest-growing language on Tiobe’s monthly index of programming language popularity. C# may eventually surpass Java in popularity, Tiobe surmised.
In the latest Tiobe Programming Community index, published November 10, C# was rated at 7.65%, an increase of 2.67 percentage points from a year ago. With its high growth rate, C# could become Tiobe’s language of the year for 2025, a designation given to the language with the highest ratings increase during the. C# won this award for the year 2023.
“How did C# achieve this? Java and C# are battling for a long time in the same areas,” said Tiobe CEO Paul Jansen, in a bulletin accompanying this month’s index. “Right now it seems like C# has removed every reason why not to use C# instead of Java: it is cross-platform nowadays, it is open source, and it contains all new language features a developer wants. While the financial world is still dominated by Java, all other terrains show equal shares between Java and C#,” Jansen wrote. Furthermore, Microsoft is going strong and C# is still Microsoft’s most-backed programming language, Jansen noted.
