WCF:为什么通过配置文件传递相同的端点时,远程端点的传递失败？

这有效:

    Using con As New OfferingTap.OfferingTapClient(New ServiceModel.InstanceContext(callback), "NetTcpBinding_IOfferingTap"

这不是:

    Using con As New OfferingTap.OfferingTapClient(New ServiceModel.InstanceContext(callback), "NetTcpBinding_IOfferingTap", "net.tcp://qa1offerings:8190/")

配置文件摘录:

        <endpoint address="net.tcp://qa1offerings:8190/" binding="netTcpBinding"
            bindingConfiguration="NetTcpBinding_IOfferingTap" contract="OfferingTap.IOfferingTap"
            name="NetTcpBinding_IOfferingTap">

例外:

  Message="A call to SSPI failed, see inner exception."

据我所知,我需要创建一个IValueConverter自定义格式.问题是我的格式是单向的,没有合法的ConvertBack实现.

那么,我该如何处理单向问题IValueConverter.(如果有帮助,这是一个只读控件.)

什么可以阻止MSTest并行运行？我将parallelTestCount设置为0,但它仍然一次运行一个测试.

这是我的发言

IF (@UserName IS NULL AND @EditorKey IS NULL) OR (@UserName IS NOT NULL AND @EditorKey IS NOT NULL) BEGIN
    RAISERROR ('One of @UserName, @EditorKey must be non-null.', 15, 0)
    RETURN
END

我想要的是能够做这样的事情:

IF (@UserName IS NOT NULL) XOR (@EditorKey IS NOT NULL) BEGIN
    RAISERROR ('One of @UserName, @EditorKey must be non-null.', 15, 0)
    RETURN
END

对于两个参数来说,这并不是什么大不了的事,但是有些过程有三个或四个只有一个可以传递,其余的应该为空.

我正在为.NET寻找一个好的HTML文档生成器.Sandcastle我的需求太复杂,太麻烦,NDoc已经死了多年.

我的一个要求是它还应该处理代码约定,它们作为编译器发出的XML文件中的额外元素公开.

如何告诉控件或控件块不继承任何样式并恢复为默认值？

我需要这个,因为我有一个主要的主题,但是一件作品真的搞砸了我的设计.

假设我的版本号为1.5.*,编译为1.5.4735.28467.

获得4735和28467的公式是什么？

1. 我如何知道我的列表是否正在虚拟化？

2. 如何将此代码段虚拟化？

   <ScrollViewer Grid.Column="1" Name="LogScroller">

我在输出窗口中得到了这个:

System.Windows.Data错误:4:无法找到绑定源,引用'RelativeSource FindAncestor,AncestorType ='System.Windows.Controls.ItemsControl',AncestorLevel ='1''.BindingExpression:路径= VerticalContentAlignment; 的DataItem = NULL; target元素是'ListBoxItem'(Name =''); target属性是'VerticalContentAlignment'(类型'VerticalAlignment')

这是我的XAML,运行时看起来是正确的

        <GroupBox Header="Grant/Deny Report">
            <ListBox ItemsSource="{Binding  Converter={StaticResource MethodBinder}, ConverterParameter=GrantDeny, Mode=OneWay}">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <Label Content="{Binding Entity}"/>
                            <Label Content="{Binding HasPermission}"/>
                        </StackPanel>
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>
        </GroupBox>

在接受WPF/Silverlight开发工作的面试中,您希望有人知道什么样的问题？
