A property on a type deriving from xref:Microsoft.AspNetCore.Components.ComponentBase annotated with [Parameter]
is being assigned to from outside the component.
Component parameters should be assigned to as part of the component initialization or as part of SetParametersAsync
. Assigning a value to a parameter from an external source results in the value being overwritten the next time the component renders.
Consider using a distinct property to receive values from other components. Additional code can then be written to decide which of the two values to use in the component.
Do not suppress a warning from this rule.
