命名空間「clr -....」中不存在名稱「DoublerConvert」

我意識到還有其他問題具有相同的標題，但是我嘗試了所有這些解決方案都無濟於事。我正在嘗試使用我製作的轉換器。我的其他轉換器工作正常，這個新的是一個前一個複製粘貼，名稱已更改，返回值更改。命名空間「clr -....」中不存在名稱「DoublerConvert」

XAML

xmlns:local="clr-namespace:ARC" 
    <local:DoublerConvert x:Key="DoubleConverter"/> 'Doesn't work 
    <local:ValueConverter x:Key="NegativeConverter"/> 'Works fine

CODE

Public Class ValueConverter 
    Implements IValueConverter 

    Public Function ProvideValue(serviceProvider As System.IServiceProvider) As Object 
     Return Me 
    End Function 

    Public Function Convert(value As Object, targetType As Type, parameter As Object, culture As CultureInfo) As Object Implements IValueConverter.Convert 
     Dim OldWidth As Integer = value 
     OldWidth = -OldWidth 
     Return OldWidth 
    End Function 

    Public Function ConvertBack(value As Object, targetType As Type, parameter As Object, culture As CultureInfo) As Object Implements IValueConverter.ConvertBack 
     Throw New NotImplementedException 
    End Function 
End Class 

Public Class DoublerConvert 
    Implements IValueConverter 

    Public Function ProvideValue(serviceProvider As System.IServiceProvider) As Object 
     Return Me 
    End Function 

    Public Function Convert(value As Object, targetType As Type, parameter As Object, culture As CultureInfo) As Object Implements IValueConverter.Convert 
     Dim OldWidth As Integer = value 
     Return 2 * OldWidth 
    End Function 

    Public Function ConvertBack(value As Object, targetType As Type, parameter As Object, culture As CultureInfo) As Object Implements IValueConverter.ConvertBack 
     Throw New NotImplementedException 
    End Function 
End Class

您是否確保重建包含轉換器代碼的程序集？ – WildCrustacean

是的，我有。我嘗試過清洗，重建以及全部保存>退出>再次啓動VS>清理>重建 – JosephGarrone

這兩個類是否包含在相同的代碼文件中？仔細檢查兩者是否具有相同的名稱空間定義。這是一個常見的問題，像轉換器那樣移動，但它們的名稱空間沒有更新，然後當您在新位置添加新的名稱空間時，即使它們位於同一文件夾中，名稱空間也不同於原始位置。 –
