The C# questions were only shown to the developers who chose C# as one of their three primary programming languages.


What versions of C# do you regularly use?

Khalid Abuhakmeh.NET Developer Advocate at JetBrains

“In my experience, developers target newer versions of C# but don’t use all of the language features immediately. ReSharper and Rider’s language usage opportunity inspections and quick fixes are a great way to learn about the latest additions to C#.”

Which programming languages are you using in your .NET project?

Maarten Balliauw.NET Developer Advocate at JetBrains

“It seems that nowadays .NET developers mostly do C# combined with a web language (43% overall).”

What runtimes do you regularly use?

Maarten Balliauw.NET Developer Advocate at JetBrains

“There really only seem to be 2 types of .NET nowadays: the “old”, and the “new”. I hope .NET 6 will start bringing these two ecosystems together again.”
