    Hi @Frulfump,

    We currently do not support .slnx files, which is why they are missing from the page you link to.

    Hi @Frulfump,

    @jketema Oh, when is the support expected? .NET 10 launched yesterday and now default to .slnx files.
    when the bug dotnet/sdk#51669 is fixed

    We'll look into this as part of our C# 14/.NET 10 support, but I cannot tell at this point when we will have support for this.

    Just to add, the change that adds support will need to make its way into a CodeQL release before it has an effect. Based on our release schedule, I'd expect this to be in CodeQL 2.24.0 that is expected for around 23 January.
