C# Extension Missing Support for .slnx Solution Files

Feature request for product/service

Anysphere Extensions (Remote SSH, Python, Dev Containers, WSL, C/C++/C#)

Describe the request

Hello,
I’ve noticed that the C# extension in Cursor doesn’t currently support .slnx files (the new XML-based solution format introduced in .NET 9).

Issue:
When using the .NET: Open Solution command, only .sln files are displayed as options. .slnx files are not recognized or shown in the file picker.

Expected Behavior:
The .NET: Open Solution command should detect and allow opening both .sln and .slnx solution files.

It would be great to see .slnx support added to improve compatibility with modern .NET projects. Thanks!
