Açıklamalar

.NET Framework 4.6'dan başlayarak sınıfının uygulanması PersianCalendar gözlemsel algoritmadan Hicri güneş algoritmasına dönüştü. Sonuç olarak, IsLeapYear yöntem .NET Framework 4.6'da çalıştırıldığında, .NET Framework önceki sürümlerinde çalıştırıldığından farklı değerler döndürebilir.
