How do I select the folders that I want to exclude?

How do I select the folders that I want to exclude?

Just run the software inside the folder you want to add excluded Folder

for the using System.Management.Automation

Try to check Nuget packages and install the correct one

Thanks for your help, and how could I make it exclude the desired folder (s)?

nuget package cake.powershell is the only one that asks but it still doesn't work, after compiling and running as administrator it doesn't work for me

I have installed nuget package System.Management.Automation but it doesn't exclude the folder either

thanks for the help i already got it working

Sorry to bother you again, is there a way to hide the cmd window during execution?

Try commenting out these two lines

                //Console.WriteLine(path+" to Windows Defender [added][+]");
                //Console.Read();

Thanks for your help, the black cmd window still appears for a short time, but it's much better.

• Open the properties of your project by right-clicking on your project in the Solution Explorer and selecting 'Properties'.
• Go to the 'Application' tab.
• Change the 'Output type' dropdown to 'Windows Application'.

This will prevent a console window from showing up, but it will still allow your application to run.
