Merhaba,<\/p>\n

Bu i\u00e7eri\u011fimizde .NET 6 ile gelen WebApplicationBuilder<\/em>‘\u0131 teknik olarak inceleyecek ve ayn\u0131 i\u015flevselli\u011fe sahip olan generic Host<\/em> ile aralar\u0131ndaki benzerlikleri de\u011ferlendirece\u011fiz.<\/p>\n

Bir \u00f6nceki .NET 6\u2019da Yeni Gelen WebApplication\/WebApplicationBuilder\u2019\u0131 Eski Generic Host \u0130le Kar\u015f\u0131la\u015ft\u0131rma<\/a> ba\u015fl\u0131kl\u0131 makalemizden de biliyorsunuz ki, Asp.NET Core uygulamalar\u0131n\u0131 olu\u015fturman\u0131n ve aya\u011fa kald\u0131rman\u0131n yeni yolu WebApplication<\/em> ve WebApplicationBuilder<\/em> nesnelerinden ge\u00e7mektedir. Ayr\u0131ca .NET 6’da, geleneksel ‘Program.cs’ ve ‘Startup.cs’ b\u00f6l\u00fcnmesi yerine t\u00fcm bootstrap yap\u0131lanmas\u0131 ‘Program.cs’ \u00fczerinde geli\u015ftirilmekte ve Top-Level Statements<\/a>, Implicit Using vs. gibi \u00e7e\u015fitli g\u00fcncellemeler e\u015fli\u011finde uygulaman\u0131n ba\u015flang\u0131c\u0131 hem zahiren, hem de bat\u0131nen sadele\u015ftirilmi\u015f bulunmaktad\u0131r.<\/p>\n

Yukar\u0131da referans edilen makalemizde WebApplication<\/em> ve WebApplicationBuilder<\/em> t\u00fcrleri hakk\u0131nda yap\u0131land\u0131rmaya dair hasbihalde bulunmu\u015ftuk. Bu i\u00e7eri\u011fimizde ise generic Host ile ayn\u0131 esneklik ve i\u015flevselli\u011fe sahip olan bu nesnelerin daha basit API’lar\u0131 nas\u0131l sunabildi\u011fini inceleyece\u011fiz.<\/em><\/p><\/blockquote>\n

\u015eimdi, her \u015feyden \u00f6nce WebApplicationBuilder<\/em> i\u00e7erisinde tan\u0131ml\u0131 olan ‘WebHostbuilder.WebHost<\/code>‘ ve ‘Hostbuilder.Host<\/code>‘ komutlar\u0131 \u00fczerine konu\u015farak konuya giri\u015f yapal\u0131m.<\/a>‘WebHost’ ve ‘Host’ komutlar\u0131 s\u0131ras\u0131yla ‘IWebHostBuilder’ ve ‘IHostBuilder’ aray\u00fczlerinden t\u00fcreyen ve bunun yan\u0131nda ‘ConfigureWebHostBuilder’ ve ‘ConfigureHostBuilder’ t\u00fcrlerinden nesne sa\u011flayan iki property’dirler.
