Ahead of Time(AOT) compilation, .NET 8’de ba\u015fl\u0131ca \u00fczerinde odaklan\u0131lm\u0131\u015f \u00f6zelliklerden birisidir diyebiliriz. Malumunuz, AOT ile derlenmi\u015f .NET uygulamalar\u0131nda Just in Time(JIT) compilation yoktur ve t\u00fcm derleme compile time’da ger\u00e7ekle\u015ftirilmektedir. Bunun, uygulaman\u0131n ba\u015flang\u0131\u00e7 s\u00fcresi a\u00e7\u0131s\u0131ndan avantaj sa\u011flad\u0131\u011f\u0131n\u0131 bildi\u011fimiz gibi uygun olmayan noktalarda ister istemez dezavantajlar\u0131 oldu\u011funu da bilmekteyiz. Misal olarak; JIT’in olmamas\u0131 demek ‘Plugin Architecture’ tabanl\u0131 uygulamalar\u0131n olmamas\u0131 demektir.<\/p>\n

.NET 8’de minimal api’leri AOT ile uyumlu hale getirebilmek i\u00e7in source generator’lar\u0131 kullanabilece\u011fimiz farkl\u0131 bir yakla\u015f\u0131m sergilememiz gereklidir. Peki bu ne demektir?<\/em><\/strong>, yani bizler a\u015fa\u011f\u0131daki gibi zaten minimal api’lar\u0131 tan\u0131mlayabiliyor ve kullanabiliyoruz;<\/p>\n

B\u00f6ylece AOT dostu metotlar olu\u015fturulmakta ve reflection tabanl\u0131 API’lara nazaran bunlar tercih edilmektedir.<\/p>\n
Minimal API Source Generator’\u0131 Etkinle\u015ftirme<\/h3>\n
Minimal api source generator’\u0131n temel amac\u0131 AOT dostu olmakt\u0131r. Bunun i\u00e7in yap\u0131lmas\u0131 gereken, uygulamada ‘PublishAot’ \u00f6zelli\u011fini <PublishAot>true<\/PublishAot><\/code> \u015feklinde etkinle\u015ftirmektir. Bu yap\u0131land\u0131rma neticesinde source generator uygulamada otomatik olarak aktifle\u015ftirilmi\u015f olacakt\u0131r.<\/p>\n
AOT a\u00e7\u0131k\u00e7a source generator’\u0131n ana odak noktas\u0131d\u0131r lakin AOT kullanmas\u0131n\u0131z bile ba\u015flang\u0131\u00e7 zaman\u0131 a\u00e7\u0131s\u0131ndan iyile\u015ftirmeleri g\u00f6rebilirsiniz. Minimal api’ler, her handler’\u0131n RequestDelegate<\/code> kodunu runtime’da dinamik olarak olu\u015fturmak yerine, source generator ile bunu \u00f6nceden de yapabilirler ve b\u00f6ylece ba\u015flang\u0131\u00e7 ve ilk istek s\u00fcrelerini h\u0131zland\u0131rabilirler. Bunun i\u00e7in .csproj dosyas\u0131nda <EnableRequestDelegateGenerator>true<\/EnableRequestDelegateGenerator><\/code> yap\u0131land\u0131rmas\u0131 e\u015fli\u011finde minimal api’lar da source generator’\u0131 etkinle\u015ftirebilirsiniz.<\/p>\n
