[.NET Core] Publish 一個 ASP.NET Core 應用程式

接續上一篇已經創建好一個ASP.NET Core的專案，這篇要來教如何 Publish，有了這一步才能將其部屬到其他平台上運作。

(環境：Windows 10, Visual Studio Enterprise 2019(16.7.2), .Net Core 3.1)

1. 開啟 cmd 進到專案的資料夾裡

   C:\>cd C:\Users\wrxue\source\repos\CorePractice
   

2. 使用 Release 組建組態並以指令 publish，下方紅色資訊為該專案 publish 出來的資料夾位置

   C:\Users\wrxue\source\repos\CorePractice>dotnet publish -c Release
   Microsoft (R) Build Engine version 16.7.0+b89cb5fde for .NET
   Copyright (C) Microsoft Corporation. All rights reserved.
   
     Determining projects to restore...
     All projects are up-to-date for restore.
     CorePractice -> C:\Users\wrxue\source\repos\CorePractice\CorePractice\bin\Release\netcoreapp3.1\CorePractice.dll
     CorePractice -> C:\Users\wrxue\source\repos\CorePractice\CorePractice\bin\Release\netcoreapp3.1\CorePractice.Views.dll
     CorePractice -> C:\Users\wrxue\source\repos\CorePractice\CorePractice\bin\Release\netcoreapp3.1\publish\
   

3. 開啟 publish 內的應用程式，此時應用程式在「http://localhost:5000」監聽囉，開啟瀏灠器輸入即可連線

   C:\Users\wrxue\source\repos\CorePractice\CorePractice\bin\Release\netcoreapp3.1\publish>dotnet CorePractice.dll #這裡是dll，不是exe
   info: Microsoft.Hosting.Lifetime[0]
         Now listening on: http://localhost:5000
   info: Microsoft.Hosting.Lifetime[0]
         Now listening on: https://localhost:5001
   info: Microsoft.Hosting.Lifetime[0]
         Application started. Press Ctrl+C to shut down.
   info: Microsoft.Hosting.Lifetime[0]
         Hosting environment: Production
   info: Microsoft.Hosting.Lifetime[0]
         Content root path: C:\Users\wrxue\source\repos\CorePractice\CorePractice\bin\Release\netcoreapp3.1\publish
   

   (注意：根目錄為執行指令「dotnet CorePractice.dll」時的目錄)
