Compilation error after migration to .Net Core

[radekcerny2]

We are re-platforming from .Net framework to .Net 7 and are getting this error

[Compilation error: The type name 'Regex' could not be found in the namespace 'System.Text.RegularExpressions'. This type has been forwarded to assembly 'System.Text.RegularExpressions, Version=0.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' Consider adding a reference to that assembly.

How can we add that reference?
