Ho to avoid 'Selector has alread been set'?

[handcraftedsource]

I used the new feature IStateSelector<TState, TValue>.

I have called Select in OnInitializedAsync of the Component on the injected property. The component is instantiated multiple times. If I switch from the first to the second component, I get an exception.

Is there any way to determine if selector is already set?

OnInitializedAsync is being executed multiple times on the same object instance?

I have a small example here that can be used to reproduce the behavior. Just start the application and switch to the counter page.

Another thing I noticed: it seems like I can't use IStateSelection alone, the component needs to have IState injected as well.

AddScoped should have been AddTransient.

I have added some other new things in there too, but need to write some unit tests when I am not busy.

Could you try 5.1.0-Beta1 and let me know if it solves your problem?

Yes the problem seems to be fixed with this version. Thanks for the quick fix. 👍
