VSCode: Could not publish the package to the server

Hi all,
I've just started my first steps with development in vscode, but currently facing a problem with the deployment I can't get around.

I have a NAV 2018 instance available on a local server
I've installed vscode and the AL Language Extension, Version 0.12.15355
I've created the HelloWorld demo project from the AL!GO template
I was able to download symbols from my local server instance so the compiler does resolve references and does not show any compile errors anymore.

But when I finally try to deploy the demo extension to my local server using F5 or Ctrl+F5, I receive the following error:
"Error: File h:\Work\ALProjects\TestATO001\MyCompany_TestATO001_1.0.0.0.app does not exist".

Run Build Task (Ctrl+Shift+B) returns the message "No build Task to run found."
I assume there's a piece missing in my build and deployment procedure but I cannot locate the issue.

Any hints what's missing here ?

Many thanks in advance
AndrewT
