החבילות בנוגט עושות לי שגיאות בהתקנה
כגון

Severity	Code	Description	Project	File	Line	Suppression State
Error		Could not install package 'PDFiumCore 123.0.6309'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.8', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

אין לי מספיק ניסיון כדי לדעת ולהבין מה בדיוק הבעיה קראתי שצריך להוסיף את ה-dll של pdfium אבל לא הבנתי בדיוק איך
אשמח לקבל עזרה
