NBMsgPack071: UseComparerAttribute member name must point to a valid property

When UseComparerAttribute specifies a member name, it must point to a public property on the specified type.

Example violation

[GenerateShape]
public partial class MyType
{
    [UseComparer(typeof(MyComparerProvider), "Comparer")]
    public HashSet<string> MyHashSet { get; set; } = new();
}

internal class MyComparerProvider
{
    private static IEqualityComparer<string> Comparer => StringComparer.OrdinalIgnoreCase;
}

Resolution

Ensure the member name points to a public property:

[GenerateShape]
public partial class MyType
{
    [UseComparer(typeof(MyComparerProvider), nameof(MyComparerProvider.Comparer))]
    public HashSet<string> MyHashSet { get; set; } = new(MyComparerProvider.Comparer);
}

internal class MyComparerProvider
{
    public static IEqualityComparer<string> Comparer => StringComparer.OrdinalIgnoreCase;
}
