-### 安裝
+### 安裝 [下載連接](https://visualstudio.microsoft.com/zh-hant/vs/compare/)
+### 下載後，若單純架設網站選擇ASP.NET 與 Node.js(之後寫Vue會用到)
+### 若需要維護Winform 或是WPF 則選擇.NET桌面開發

+
+### 若需要快速建立，則直接使用我提供的DEMO去做開發
+### 建立新專案

+
+### 選擇版本 (這邊以.NET6做教學 目前最新的.NET8)
+![](http://140.125.21.65:8418/Education/Backend/raw/branch/master/C_shape/img/%E5%9C%96%E7%89%873.png)

+### 安裝套件包(NuGet)

+### 設定資料庫連線
+#### 於appsettings.json 中加入
+```
+//連接MYSQL
+  "ConnectionStrings": {
+    "tarefasConnection": "server=140.125.21.65;port=3307;uid=VIP125;pwd=@VIPvip125;database=VIP125"
+  }
+```
+![](http://140.125.21.65:8418/Education/Backend/raw/branch/master/C_shape/img/%E5%9C%96%E7%89%876.png)
+
+#### 於Program.cs中加入設定
+```
+	builder.Services.AddDbContext<SqlContext>(opt =>
+{
+    string connectionString = builder.Configuration.GetConnectionString("tarefasConnection");
+    var serverVersion = ServerVersion.AutoDetect(connectionString);
+    opt.UseMySql(connectionString, serverVersion);
+});
+```
+![](http://140.125.21.65:8418/Education/Backend/raw/branch/master/C_shape/img/%E5%9C%96%E7%89%877.png)
+### 建立與資料庫table的連線
+#### 創建Model
+	建議將創建的Model名稱第一個字大寫，資料庫內部資料表名用小寫，這樣較好對比
+    Model內容需要跟資料表的欄位名稱相對應
+    
+![](http://140.125.21.65:8418/Education/Backend/raw/branch/master/C_shape/img/%E5%9C%96%E7%89%879.png)
+#### 創建Services
+	Haskey指的是不會重複的
+    像是身份證字號這種的就不會重複
+![](http://140.125.21.65:8418/Education/Backend/raw/branch/master/C_shape/img/%E5%9C%96%E7%89%878.png)
+
+### 創建控制器
