Visual Studio调试ASP.NET Core+React容器化应用的Dockerfile疑问

我使用“ASP.NET Core with React.js”模板创建了一个简单的ASP.NET Core+React Web应用并进行容器化。Release配置运行时一切正常，但Debug配置运行时，环境变量未正确设置，且npm项目未完成配置。

经调研，这是因为Visual Studio/MSBuild在Debug配置构建时不会执行Dockerfile的所有阶段。

我已尝试以下解决步骤：

• 添加<ContainerDevelopmentMode>Regular</ContainerDevelopmentMode>
• 添加<DockerfileFastModeStage>final</DockerfileFastModeStage>
• 删除所有Docker镜像、卷和容器

我发现添加到Base阶段的所有内容都会应用到Debug容器中，对此我无法理解。

想请教以下问题：

1. Visual Studio/MSBuild在Debug模式下实际使用的镜像包含哪些阶段？
2. 若未执行所有阶段，源代码如何传入镜像/容器？
3. 若仅构建Base阶段，容器内部使用的入口点是什么？

我的Dockerfile如下：
