Rule S6803 is invalid

[davidmilligan]

Description

Rule S6803 states that: Parameters with SupplyParameterFromQuery attribute should be used only in routable components. Component parameters can only receive query parameter values in routable components with an @page directive.

This logic is invalid because any component can potentially be a routable component because any component can inherit from another component and add an @page directive, which would then make the [SupplyParameterFromQuery] from the inherited component once again valid/meaningful.

This rule should be either removed entirely or only apply to components that are sealed (there is no razor syntax for sealing a component, so I imagine this is a very uncommon occurrence)

Hello @davidmilligan,

Thanks a lot for your feedback.

Indeed, what you mention is correct.
We decided to deprecate the rule (see issue here).
In the next release, this rule will be removed from the default quality profile so no issues will be raised.
