✅ Blazor and Javascript loading

So, I have a main page and a separate adminpage. On navigating to the admin site it changes the layout to AdminLayout.razor which inherits from @inherits LayoutComponentBase. So far, so good, the adminpage inlcudes @layout AdminLayout and everything is displayed correctly. The AdminLayout also has several JS includes at the end of body. It seems that after first navigation those scripts aren't loaded, the behaviour is as followed: - Navigate to admin page - Click on a <a href="#"> that should expand a collapsed div, but it doesn't - Reload/Refresh the page after it's initial load and it works as expected Switching the rendermode to Server and Server without prerender haven't helped here. Navigating to the adminpage via NavigationManager, could this be an issue?

✅ Blazor / ASP.NET - @inject keyed service

Is there a way in .NET 8 to inject a keyed service like a normal service with the @inject keyword? I know of the FromKeyedServices attribute, but cannot figure out how to use it in combination with @inject. I thought of a way like @inject [FromKeyedServices("MyService")] ServiceClass FooBar;

Yet another question about struct & class

So, here I am, having this code

public readonly record struct MinifigureDto {
    public required int Id { get; init; }
    public required string Name { get; init; }
    public required int ThemeId { get; init; }
    public required uint Amount { get; init; }
}

public readonly record struct MinifigureDto {
    public required int Id { get; init; }
    public required string Name { get; init; }
    public required int ThemeId { get; init; }
    public required uint Amount { get; init; }
}

This object won't change during runtime, so, should I make it a struct or a class? What is the devil in the detail?

The best-practice way to use a plausibility check

So, I have the following class

namespace CleanLib.Lego.Parts;

public class Color : Entity {
    private string? _Name;
    public string Name {
        get => this._Name!;
        set {
            value.ThrowIfNullOrWhiteSpace();

            this._Name = value;
        }
    }

    private string? _Code;
    public string Code {
        get => this._Code!;
        set {
            value.ThrowIfNullOrWhiteSpace();

            this._Code = value;
        }
    }

    public Color(string name, string code) {
        this.Name = name;
        this.Code = code;
    }
}

namespace CleanLib.Lego.Parts;

public class Color : Entity {
    private string? _Name;
    public string Name {
        get => this._Name!;
        set {
            value.ThrowIfNullOrWhiteSpace();

            this._Name = value;
        }
    }

    private string? _Code;
    public string Code {
        get => this._Code!;
        set {
            value.ThrowIfNullOrWhiteSpace();

            this._Code = value;
        }
    }

    public Color(string name, string code) {
        this.Name = name;
        this.Code = code;
    }
}

Is it okay to throw in the setter of the properties or is it somehow "better" to check this in the constructor? Logically spoken, both values won't ever change, but may be "corrected" if inserted wrongly in the database.

Is "System.IO.IsolatedStorage" still a thing in .NET?

I'm wondering if the usage of Isolated storage is still something, someone could consider using today. Plus, is there finally a way to make it persistent across version changes of the application, or do we still need an "updater" software? However, I'm free to hear some alternatives 🙂 How you would store a local Highscore Database/File?
