Wouldn't it better to make just

public record BreadcrumbItem(string Text, string? Href, bool Disabled = false, string? Icon = null);

?

That's a breaking change if you reference the variable name in the constructor: new BreadcrumbItem(href: "..."). There's no href anymore.

That's very interesting, I thought the generated code would lowercase it? But seems like I'm wrong

public BreadcrumbItem([Nullable(1)] string Text, string Href, bool Disabled = false, string Icon = null)
{
            <Text>k__BackingField = Text;
            <Href>k__BackingField = Href;
            <Disabled>k__BackingField = Disabled;
            <Icon>k__BackingField = Icon;
            base..ctor();
}

No idea why would they do that, considering that record is just a "superstructure" over class.
Ty, learned something new today.

Breaking change? What to write in the migration guide?

[ScarletKuro]

I don't think it's a breaking change either? The properties were readonly already, all you added is that with record it implements ToString and Equality etc which is a good thing.

[danielchalmers]

@ScarletKuro @henon Breaks inheritance because it's no longer a class.

CS8865: Only records may inherit from records.

Migration guide could say

BreadcrumbItem is now a record and any class that inherits from it must be updated to a record as well
