標記'ViewBox'不存在於XML命名空間'http://schemas.microsoft.com/winfx/2006/xaml/presentation'

Question

我想，有一天我應該嘗試WPF。原來我在第一個障礙中倒下了。 我從Inkscape生成的xaml文件插入代碼，然後將其包裝在Viewbox標籤中。我有錯誤，它不存在於命名空間中。 我在做什麼錯？我需要某種參考嗎？

Answer 1

下面的步驟，我是能夠運行您的樣品：

• 創建一個新的WPF項目;

• 在打開的自動創建的窗口中，我刪除了<Grid></Grid>對象;

• 我將其替換爲您的代碼示例。

這工作成功。以下是結果：
