@* Foo.razor *@
@code {
    [Parameter(CaptureUnmatchedValues = true)]
    public IReadOnlyDictionary<string, object>? AdditionalAttributes { get; set; }
}

Produces:

Components_Pages_Home_razor.g.cs(100,13): Warning MA0115 : The parameter 'Bar' does not exist on component 'BlazorComponentLifecycle2.Components.Foo'. Available parameters: AdditionalAttributes. (https://github.com/meziantou/Meziantou.Analyzer/blob/main/docs/Rules/MA0115.md)

By default the rule reports unmatched pascal case parameters. You can disable it by using the .editorconfig:

MA0115.ReportPascalCaseUnmatchedParameter = false
