This rule is deprecated, and will eventually be removed.
Component parameters can only receive query parameter values in routable components with an @page directive.
Why is this an issue?
SupplyParameterFromQuery
attribute is used to specify that a component parameter of a routable component comes from the query string.
In the case of non-routable components, the SupplyParameterFromQuery does not contribute to the functionality, and removing it will
not affect the behavior.
How to fix it
Either make the component routable or remove the SupplyParameterFromQuery attribute.
Code examples
Noncompliant code example
<h3>Component</h3>

@code {
    [Parameter]
    [SupplyParameterFromQuery]  // Noncompliant
    public bool Param { get; set; }
}

Compliant solution
@page "/component"

<h3>Component</h3>

@code {
    [Parameter]
    [SupplyParameterFromQuery]  // Compliant
    public bool Param { get; set; }
}
