Let's assume you are on the folder that contains the project. Change to the directory of the PuppetMaster

cd .\DAD\PuppetMaster\  

Run the program using dotnet

dotnet run

Now you are on the GUI of the Puppetmaster and you can run any commands you want by clicking the buttons.
To run a script:

Click on the <Run Script> button  

Select the script you want to run (there is a sample script in the root folder of the project)  

Press <Abrir> or <Open> depending on your System's language  

The script will start running

You can still order new commands after running a script
