Im currently writing a Contact Manager for our Exchange Online Tenant in C# using the Powershell-Commands and Runspaces from "System.Management.Automation" and "System.Management.Automation.Runspaces" respectively. Its working fine for adding Contacts to the GAL. But im stuck at editing Contacts.

I need to get the Contact Details with the Powershell Commands. The code i can execute looks like this:

im working on a project for school where we are supposed to create a Contact book. I stumbled on to a problem where my program prints out strings as hexa symbols, i have never encountered this before and have no idea on how to combat it.

The strings are getting printed out on the terminal from an array.

So in the following code PMD tells me the that the Scanners keyboard and scan are unclosed with a [CLoseResource] warning. I think I close I made sure that it is always closed, so I don't know what is causing this warning. The code itself works fine, and those are the only serious warnings PMD is throwing at me.

I have a question about bindings. I have tried binding my second view to a Viewmodel in an empty app with the help of fody.propertychanged because I did it in my project I have and it didn't work.

So, I did a clean slate and retried and this is still not working. I have no clue to why it is not working; this is what I have tried this far.

Its session beans wich i have managed to create and i can call upon it. the logic in it self seems to work. The issues im having is one of the follow ups seems to forget what it was doing.
the curren tissue im seeing is the following:
In the Web application in an class we are creating an object of Another class wich we then trigger its parent method. this parent method then calls upon a class with it self as an argument wich then checks wich type it is and then stars a session bean depending on what type. wich then calls on the arguments function performExecute() in this function we call upon a Query and actually get the correct results, we then add the resultsets values to a private dto member. and then performExecute is done. and we are back at the web applications class and we then try to acces the same dto member with a get function. this returns a nullpointer. I'm wondering if I've forgotten something in my session beans?
