Subclassing a UserControl

Question

我正在尝试子类化UserControl后阅读以下内容:WPF UserControl如何继承WPF UserControl?

但我似乎错过了什么。

基类，它不是局部的，也没有XAML:

namespace HTTPFreeForm
{
    public class HTTPBaseForm : UserControl, IForm
    /* ... more content ... */
}

子类后台代码:

namespace HTTPFreeForm
{
    public partial class HTTPFreeForm : HTTPBaseForm
    /* ... more content ... */
}

子类XAML:

<local:HTTPBaseForm x:Class="HTTPFreeForm.HTTPFreeForm" 
             xmlns:local="clr-namespace:HTTPFreeForm"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             mc:Ignorable="d" 
             d:DesignHeight="300" d:DesignWidth="300">
    <!-- ... more content ... -->
</local:HTTPBaseForm>

当我尝试构建，我收到以下错误:

错误2类型名称"HTTPBaseForm"不存在于类型"HTTPFreeForm"中。HTTPFreeForm' c:MyProjectHTTPFreeFormobjDebugHTTPFreeForm.g.cs 42 54 HTTPFreeForm

我错过了什么或做错了什么?

名称冲突，命名空间与类命名相同。改变一下，再试一次。
