接續之前寫的：
1. 在CentOS 7使用CSharp開發程式的前置條件(安裝.NET 7)
2. 在CentOS 7上使用Visual Studio Code開發標準C語言程式
這裡紀錄在CentOS 7上使用VSCode 1.74開發CSharp程式
Step1:影片00:01，啟動VSCode，安裝輔助外掛工具，搜尋CSharp即可看到
Step2:影片00:38，建立專案資料夾/CSharp/UnitTest001
Step3:影片01:33，在專案資料夾內建立.vscode資料夾，預設是個隱藏資料夾，檔案總管看不到
Step4:影片02:30，指令ll -a或ls -a可以看到隱藏資料夾
Step5:影片09:30，在專案資料夾內輸入dotnet new console --use-program-main，建立不使用最上層語句(top-level statements)且具有Main方法的主控臺專案
(這裡先以舊式的CSharp寫法當範例，如果不帶參數--use-program-main，會使用.NET 6開始的新風格，最上層語句)
Step6:影片12:19，把UnitTest001.csproj內的ImplicitUsings改為disable
(enable時有些using指示詞會被隱藏，細節請參考微軟的介紹
)
Step7:影片17:50，指令dotnet restore，在.vscode資料夾內建立launch.json和tasks.json
Step8:影片17:52，先設定中斷點(breakpoint)，再輸入指令dotnet run，執行並偵錯程式
Step9:影片17:56，中斷點攔截成功，第一個CSharp程式，HelloWorld正常執行
