如何使用VS創建新的Web Part項目

Web Part是你將為SharePoint創建的最常見的對象之一。它是平台構建的核心基塊。

1. 管理員身份打開Visual Studio，新建空白SharePoint項目。命名WroxSPProject，點擊確定。部署為場解決方案，點擊完成。

2. 右擊選擇添加新項目Web Part，命名SimpleWebPart，點擊添加。

3. 在進一步前進之前，點擊生成----部署解決方案。

此時，你將發現VS添加了許多項目到解決方案中。例如，它增加了feature1.feature。新的節點SimpleWebPart也被添加，它包含了許多文件。盡管你看不到，許多配置XML也更新了。

如果你雙擊feature節點，將打開Feature Designer。它提供了組成當前WSP包的feature圖形化視圖。以及設置部署層次（如網站或場）。你可以從這個視圖添加或移除feature。配置部署選項以及編輯XML。因為你只添加了一個Web Part，所以只有顯示一個feature。

1. 導航到SimpleWebPart.webpart，雙擊進入代碼視圖。修改屬性。

2. 打開SimpleWebPart.cs。修改代碼。
