Question

我的 aspnetcore docker 项目构建，但是当我单击 Docker 按钮（或按 F5）到运行我得到

Severity    Code    Description Project File    Line    Suppression State
Error   MSB4018 The "PrepareForLaunch" task failed unexpectedly.

我确实使用 Docker 设置共享了 C:。我正在使用 linux 个容器

Docker文件是

FROM microsoft/aspnetcore:1.1
ARG source
WORKDIR /app
EXPOSE 80
COPY ${source:-obj/Docker/publish} .
ENTRYPOINT ["dotnet", "PsWebApi.dll"]

我已经升级到最新的 nuget 包。

Answer 1

user id和对应的email用于登录dockerhub 在这种情况下实际上是两个不同的东西。

需要用户名的 id、，而不是 email 才能获得 images。

解决

通过
在两者之间切换
> docker logout

然后在命令行上

> docker login

并使用您的 id 登录。

请注意，使用电子邮件登录后，可以在 docker 站点上找到 id。

系统将提示您输入凭据。同样，对于该用户名，不要使用电子邮件地址。

Answer 2

我在最新的 ASP.NET 核心模板中也遇到了同样的问题。以下修复对我有用。

打开 Package Manager Console window.
运行命令docker logout.

然后再次 run/debug(F5) 应用程序。

附带说明一下，您需要在 Docker 中切换到 Windows 容器。否则你会看到另一个错误：image operating system "windows" cannot be used on this platform.
