docker-compose 在 Visual Studio 中不起作用

Question

我在一个解决方案中有三个 Web 项目，它们在 gRPC 上协同工作。 我正在尝试使用 docker-compose 启动所有三个项目，但问题是当命令

docker-compose up --build

这就是一切的工作方式，但是当我尝试在连接调试器的情况下开始使用 Visual Studio 界面时，它不起作用

当您在 Visual Studio 中通过 docker-compose 运行应用程序时，当您启动容器本身时，会出现以下内容的错误：

Can't find a program for debugging in the container

然后它立即弹出这个：

The target process exited without raising an event fired by CoreCLR. Make sure the target process is configured to use .NET Core. This may be necessary if the target process has not started in .NET Core.

此消息出现在容器日志中：

Could not execute because the application was not found or a compatible .NET SDK is not installed.
Possible reasons for this include:
  * You intended to execute a .NET program:
      The application '/app/bin/Debug/net5.0/Votinger.Gateway.Web.dll' does not exist.
  * You intended to execute a .NET SDK command:
      It was not possible to find any installed .NET SDKs.
      Install a .NET SDK from:
        https://aka.ms/dotnet-download

这是一个由 Visual Studio 自动生成的 Dockerfile，除了项目的路径外，每个项目都是相同的

我会原谅你的帮助

我找到了一个解决方案，问题是在 Visual Studio 生成的 docker-compose.vs.debug.yml 文件中，那里指示了项目和调试器的完整路径，我的路径经过了一个名为 C# 的文件夹，然后Visual Studio决定把#不必要的符号算出来删掉，结果是C文件夹的路径，导致完全不同的地方
