如何在 Docker、Windows 10、WSL 2 中调试

Question

When I try to run Debug F5 from VS 2019 using Docker I see the following error

C:\Users\comet.nuget\packages\microsoft.visualstudio.azure.containers.tools.targets\1.9.10\build\Container.targets(198,5): error CTC1001: Volume sharing is not enabled. On the Settings screen in Docker Desktop, click Shared Drives, and select the drive(s) containing your project files.

I have WSL2 and latest Docker Desktop, google says that sharing is already done automatically so Desktop has no such Setting at all

Answer 1

I had the same problem with an older project. Creating a new project with docker support worked fine. The difference I found that the old project file had:

<OutputType>Exe</OutputType>

and the new project did not have that line, so I removed it. Also updated the targets:

    <PackageReference Include="Microsoft.VisualStudio.Azure.Containers.Tools.Targets" Version="1.10.9" />

This solved it for me
