当远程调试一个托管在 Windows Docker 容器上的 .NET Core 控制台应用程序时，无法通过代码进行步进。即使 PDB 文件与 DLL 存在，也会出现“找不到或打开 PDB 文件”的错误。
Dockerfile
FROM microsoft/windowsservercore
WORKDIR /
COPY ./tools ./
RUN dotnet-dev-win-x64.1.0.4.exe /install /quiet
RUN vs_remotetools.exe /install /quiet
EXPOSE 4022
COPY ./Clients/Client.Web.Identity.Client.MVC ./Clients/Client.Web.Identity.Client.MVC
WORKDIR ./Clients/Client.Web.Identity.Client.MVC
RUN dotnet restore Client.MVC.csproj
RUN dotnet build Client.MVC.csproj
CMD dotnet run http://*60720
Visual Studio 调试输出
https://pastebin.com/D77JCtr9注意第二行：
'dotnet.exe' (CoreCLR: clrhost): Loaded 'C:\Clients\Client.Web.Identity.Client.MVC\bin\Debug\netcoreapp1.1\Client.Web.Identity.Client.Mvc.dll'. Cannot find or open the PDB file.
容器输出显示 MSVSMON 运行，客户端 Web.Identity.Client.Mvc.pdb 存在于 dll 路径中。
