Docker build failed in my first .Net HelloWord App. Please Help me!

Hi people

This is my first visual studio 2019 console application with docker support (OS: Windows Server 2019). I only want to run a docker container with “hello word”. So I have created a console app with .net core and docker support. The docker file is made automatically by visual studio.
The .net solution project is in: C:\dev\test02\

Then, I go to powershell and execute the docker build command in the same machine:

PS C:\dev\test02\test02> docker build -t dkapp2 .

And it says:

The docker file build automatically buils Visual Studio is:

#Depending on the operating system of the host machines(s) that will build or run the containers, the image specified in the FROM statement may need to be changed.
