Has the System.Management changed in Visual Studio 2019?

Question

Hi there

 

I am very new to programming, but am trying to learn from online sources and a few books. Currently I am trying to create a little Inventory application and wanted to add a db to it. 

 

I have been following Tim Corey for a while and in his video about using a SQLite db in a c# application, he adds system.management as a reference to his library. 

 

I can't seem to do this, even tho it worked fine in Visual Studio 2017.

Did something change? 

I believe he is using a WinForms, while I am using a WPF. Does this matter? 

 

As I said, I am new to this, so any help would be greatly appreciated. I can add code, pictures or what else is needed - just tell me.

 

Best regards
