İyi günler, Unity üzerinden oyun geliştirmeye başladım. Editör olarak ise Visual Studio Code kullanıyorum fakat, Unity ile ilgili tüm eklentileri kurmama rağmen kodlarım otomatik olarak tanımlanmıyor (IntelliSense Çalışmıyor). Birde kurduğum C# eklentisi üzerinden bir hata veriyor, galiba bu hatadan dolayı çalışmıyor.
Hatanın konsol çıktısı;
