Here is a solution for ASP.NET Core 2+ and ASP.NET Core 3+. Add it into IAsyncAuthorizationFilter implementation:

private static bool HasAllowAnonymous(AuthorizationFilterContext context)
{
    var filters = context.Filters;
    return filters.OfType().Any();
}

And check like this:

public async Task OnAuthorizationAsync(AuthorizationFilterContext context)
{
    if(HasAllowAnonymous(context))
        return;
}
