I am new with docker, trying to create my first docker image/container with .net core console application in Windows 10, following the article <https://www.c-sharpcorner.com/article/getting-started-with-docker-for-windows-containerize-a-c-sharp-console-app/> 

I am getting the error message when building image:

```
COPY /bin/Debug/netcoreapp2.0/publish/ . COPY failed: CreateFile \\?\C:\ProgramData\Docker\tmp\docker-builder989987487\bin

```

The content of my Dockerfile:

```
FROM microsoft/dotnet:2.0.4-runtime-nanoserver-1709 AS base  

WORKDIR /app  
COPY /bin/Debug/netcoreapp2.0/publish/ .  

ENTRYPOINT ["dotnet", "ConsoleApp1.dll"]

```

* `C:\DotNetCore\ConsoleApp1\ConsoleApp1` is the root of my folder,
where I palced above Dockerfile.
* `C:\DotNetCore\ConsoleApp1\ConsoleApp1\bin\Debug\netcoreapp2.1\publish`
is the folder where content is get published by `dotnet publish`
command.

Command used to create the image:

```
docker build -t alphaimage .

```
