I’ve created a working component based on WinForms’ UserControl. I’ve overridden a couple of existing properties that generate warning CS8765.

CS8765: Nullability of type of parameter 'value' doesn't match overridden member (possibly because of nullability attributes).

This code places the warning on “set” .

    /// <summary>
    /// Gets or sets the font of the text
    /// </summary>
    [Browsable(true)]
    public override Font Font
    {
        get => base.Font;
        set
        {
            base.Font = value;
            AdjustSize();
        }
    }

If I change the property’s type from “Font” to “Font?” the warning for “set” goes away, but I get a different warning on “get”.

CS8764: Nullability of return type doesn't match overridden member (possibly because of nullability attributes).

This makes sense to me because the original declaration that I’m overriding uses the non-nullable version of Font.

Without ignoring it, how do I fix my original warning?
