求助：开发集成指纹认证的Windows自定义凭据提供商

我正在开发一款集成指纹认证的Windows自定义凭据提供商，具体需求：

• 使用外部指纹阅读器/软件完成用户指纹身份验证
• 必须对接Windows生物指纹API（WBF）实现与操作系统的集成

我没有Windows平台及相关API的开发经验，一直未找到适配的开源示例项目，希望有Windows凭据提供商开发经验的人士提供以下三方面的指引：

• Windows生物指纹API的使用方法
• 外部指纹阅读器/软件的集成方案
• 自定义凭据提供商的整体架构设计

若能提供完整可用的开源示例或模板，将更为理想。

我曾找到过类似问题，但答案不够清晰，缺乏指导性，对新手不友好。此外，我向ChatGPT咨询得到了一段代码，但该代码仅为框架，未实现核心功能，不够完善，代码如下：
