Should the nuget package work for a .Net 7.0.2 Blazor hosted app when using the Edge browser?

[PlanBernhard]

Hello experts!

Unfortunately I am unable to use this package to store a List in the LocalStorage in the Microsoft Edge browser. Using

(The razor file)

@inject Blazored.LocalStorage.ILocalStorageService localStorage

@code{
protected override async Task OnInitializedAsync()
    {
        await localStorage.SetItemAsync("name", "John Smith");
        var name = await localStorage.GetItemAsync<string>("name");
    }
}

Doesn't store anything. And using await _localStorage.GetItemAsync<List<CartItem>>("cart"); produces this error

CartItem model:

public class CartItem
{
    public int ProductId { get; set; }
    public int ProductTypeId { get; set; }
}

But it did work in Google Chrome

EDIT: Okay, that is strange. Chrome does only work, if the Visual Studio has not started it in debug mode. The same goes for the dotnet command. If the dotnet watch was executed the storage did not work,

but with dotnet run it did work. I cleaned an rebuilded my solution now over 10 times. And I also cleaned the whole application storage on all browsers. I don't know what is going on here.

EDIT 2: I restarted my machine, deleted every cache or binary and tried it again. The same result.

Okay, sorry. It is there. I wrote a method to output the storage. The issue seems to be the display of the devtools.
