c＃wpf多重绑定不是很流行(c# wpf Multibindings not aviable)

 我想要做的事很简单。 我有一个窗口，我希望标题绑定到两个不同的属性。 标题应在每次更改属性时进行更新。 
 
 我第一次尝试并且没有工作 
 
<Window x:Class="Giag.DataReader.ControlLibrary.Windows.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="{Binding Path=Clientname} {Binding Path=LoadedConfiguration}" 
 
 那么我在这里和这里阅读关于多重绑定。 并尝试像这样使用它实际上也不起作用 
 
<Window x:Class="Giag.DataReader.ControlLibrary.Windows.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<Window.Title>
    <Multibinding StringFormat="{}{0} + {1}">
        <Binding Path="Clientname" />
        <Binding Path="LoadedConfiguration" />
    </Multibinding>
</Window.Title>
 
 错误是多重绑定不支持WPF项目中 ，我认为没有任何意义。 
 
 所以，即时猜测是缺少xmlns或缺少.dll。 我发现Multibindings在“PresentationFramework.dll”里面，我引用了它。 根据msdn，你需要http://schemas.microsoft.com/winfx/2006/xaml/presentation或http://schemas.microsoft.com/netfx/2007/xaml/presentation包括，我做了。 
 
 在这里，我可能实际上没有更进一步，我希望你能得到。 

what i want to do is quite simple. I have got a Window and I Want the Title to be bound to two different Properties. The Title should be Updated everytime one of the Properties changes.
 
What I tried first and didnt work
 
<Window x:Class="MyNamespace.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="{Binding Path=Clientname} {Binding Path=LoadedConfiguration}" 
 
So then I read here and here about Multibindings. And tried its usage like this what actually doesnt work, too
 
<Window x:Class="MyNamespace.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<Window.Title>
    <Multibinding StringFormat="{}{0} + {1}">
        <Binding Path="Clientname" />
        <Binding Path="LoadedConfiguration" />
    </Multibinding>
</Window.Title>
 
The Error ist that Multibinding is not supported in a WPF project, what in my opinion doesnt make any sense. 
 
So, what im guessing is a missing xmlns or a missing .dll. I found out that Multibindings are inside "PresentationFramework.dll", which i have referenced. According to msdn, you need either http://schemas.microsoft.com/winfx/2006/xaml/presentation or http://schemas.microsoft.com/netfx/2007/xaml/presentation to include, which I did.
 
Here I may actually not get any further, I hope you get.
