Merhaba,<\/p>\n

Bu i\u00e7eri\u011fimizde sizlere, .NET uygulamalar\u0131nda MongoDB kullan\u0131m\u0131n\u0131 olduk\u00e7a kolayla\u015ft\u0131ran ve EF Core 8 ile hayat\u0131m\u0131za girmi\u015f olan MongoDB Entity Framework Core Provider<\/em>‘\u0131ndan bahsediyor olaca\u011f\u0131m.<\/p>\n

Malumunuz bu g\u00fcne kadar .NET uygulamalar\u0131nda MongoDB’yi kullanabilmek i\u00e7in MongoDB.Driver<\/a> k\u00fct\u00fcphanesinden istifade ediyorduk ve gerekli yap\u0131land\u0131rmalar\u0131 temel d\u00fczeyde kendimiz in\u015fa ediyorduk. Buna \u00f6rnek vermemiz gerekirse e\u011fer; bir ‘Person’ kayd\u0131n\u0131 tutabilmek i\u00e7in gerekli geli\u015ftirmeleri a\u015fa\u011f\u0131daki gibi in\u015fa edip \u00e7al\u0131\u015fmalar\u0131m\u0131z\u0131 ger\u00e7ekle\u015ftiriyorduk.<\/p>\n

Entity’i olu\u015fturuyorduk;<\/p>\n
