Call function when system time changed
I'm reading the Microsoft SystemEvents.TimeChanged and I'm having trouble understanding how to link my own function to call when the system time changes.

TimeChanged is an event, so you have to += it
SystemEvents.TimeChanged += YourMethod;
and remember to -= it when the program gets closedDoesn’t matter really for app close time.
The problem is my program isn't detecting SystemEvents? Is that a library I import?
It’s in Microsoft.Win32 https://learn.microsoft.com/en-us/dotnet/api/microsoft.win32.systemevents?view=net-8.0
SystemEvents Class (Microsoft.Win32)
Provides access to system event notifications. This class cannot be inherited.
You may need a -windows TFM for it.
Eg
net8.0-windows(that's in the
<TargetFramework> in your .csproj)I wonder where you set a windows tfm in the VS GUI.
