我正在开发 wpf C#,运行应用程序时出现此错误:这是我的代码
<Window x:Class="Hello.Testing"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:r="clr-namespace:Wpf.Controls;assembly=Wpf.TabControl"
xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
Title="Testing" Height="780" Width="1024" WindowStartupLocation="CenterScreen"
MinWidth="1024" MinHeight="780"
WindowStyle="None" AllowsTransparency="False"
ResizeMode="CanResizeWithGrip" Icon="Resources/Images/Icons/small_icon.ico" Loaded="Window_Loaded">
这是我得到的一个错误:
"Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception"
