I’d like to request official support for .NET 10 and C# 14, which were released on November 11, 2025, as announced in Microsoft’s official blog:
At the moment, Cursor’s AI models appear not to recognize or apply any of the C# 14 syntax or language features. When asked to use them, the assistant explicitly refuses, stating that they are “not supported.” In addition, when generating code for new features, it sometimes falls back to outdated syntax versions — occasionally producing patterns that resemble early experimental drafts of the language, not the final C# 14 release.
This makes it difficult to experiment with or adopt .NET 10 features within Cursor.
Could you please add full .NET 10 / C# 14 awareness and syntax support to the environment and AI models?
This update would ensure Cursor remains aligned with the latest Microsoft stack and enable developers to take advantage of new runtime, compiler, and language features.
I installed the DotRush – Open VSX Registry to be able to at least have proper syntax highlighting and linting … but there is nothing it can be done for the models except to wait.
I’ve got an Ultra subscription and I’ve spent thousands of dollars on AI through Cursor editor in the few last months. My target is mostly C# development (Blazor, WFP) with edge versions (.NET 10 and onwards).
I’m waiting for months to have a proper language server to finally replace Visual Studio on my workflows. I’ve tryed many hacks to make the official C# Dev Kit extension work. I’ve also tryed anysphere.csharp many times, but got many problems in both cases. I don’t want to pay for ReSharper, it’s out of my spcope and oversized, it has features that should be included in any decent language server by default.
That said, this thread is open for months now, as many other related to the same, but there aren’t any clear responses from Cursor team about it.
Is this the kind of support we can expect from Cursor team?
Do I have to start looking for alternatives to Cursor?
