Does Roslyn support code fix actions for project/compilation-level diagnostics (with no location)?

[Denis535]

We can report diagnostics for Compilation, SyntaxTree, SyntaxModel but those diagnostics will not have location.

private static void OnCompilation(CompilationAnalysisContext context) {
    var compilation = context.Compilation;
    var diagnostic = Diagnostic.Create( Rule, (Location) null );
    context.ReportDiagnostic( diagnostic );
}

We can also register code fixes for those diagnostics. But it looks like there is no way to execute those code fixes (there is no light bulb, I can only see it in error list window).

public sealed override Task RegisterCodeFixesAsync(CodeFixContext context) {
    var document = context.Document;
    //var span = context.Span;
    var diagnostic = context.Diagnostics.Single();
    RegisterCodeFix( context, "Fix compilation", diagnostic, Action );

    Task<Solution> Action(CancellationToken cancellationToken) {
        return Task.FromResult( document.Project.Solution );
    }
}

I even can't test such diagnostic because CodeFixContext throws ArgumentNullException when document is null.

So, can I make code fixes for a such diagnostics or not?

[CyrusNajmabadi]

No. That is not supported.

I don't understand something.
If CodeFixProvider doesn't support project-level diagnostics then why FixAllContext has GetProjectDiagnosticsAsync method?
