wsHttpBinding远程服务器返回了意外响应：（400）错误请求，WCF

Question

我正在尝试在n层架构中跨层发送两个图像（80K字节）和少量数据。

我的项目有以下图层

1. DAL - 包含CURD的所有类
2. 业务 - 包含业务组件
3. ServicesContracts - 包含服务合同（Json）
4. 服务 - 服务合同的实施
5. UI流程 - 包含服务引用（OrganizationServiceReference）
6. UI.Client - 包含客户端逻辑
7. 主机 - 包含用于托管服务的引用（DAL，业务，实体，服务，ServiceContracts）和web.config
8. 实体 - 共同实体
客户端层中的

我已经阅读了很多关于此错误的帖子，但没有任何帮助我解决问题。

请指导我正确的方向，以便我能解决这个问题。
