I just tried the link, and as I mentioned in the comments it compiles without any problem.

我刚刚尝试了这个链接，正如我在评论中提到的，它编译没有任何问题。

Can be ignored.

可以忽略。

And the preview is not available as well, I learned to live with it.

而且预览版也不可用，我学会了忍受它。

No errors when compiling

编译时没有错误

And the program starts up. No problem

然后程序启动。没问题

For me the problem was that the solution platform was set to AnyCPU.
As far as I know, CefSharp does not support AnyCPU. Interestingly the solution ran just fine in Release mode, but in Debug mode I immediately got an error - the invocation of the constructor on type that matches ... the specified binding constraints threw an exception.

对我来说，问题是解决方案平台设置为 AnyCPU。
据我所知，CefSharp 不支持 AnyCPU。有趣的是，该解决方案在 Release 模式下运行良好，但在 Debug 模式下我立即出现错误 -the invocation of the constructor on type that matches ... the specified binding constraints threw an exception.

As soon as I changed the solution platform to be only x64, then the XAML error went away (The name ChromiumWebBrowser does not exist in the namespace “clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf”). And I could run the solution both in Debug and Release mode.

一旦我将解决方案平台更改为仅 x64，XAML 错误就消失了 ( The name ChromiumWebBrowser does not exist in the namespace “clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf”)。我可以在调试和发布模式下运行解决方案。

its not supported in the XAML desginer, so load it in run time:

XAML 设计器不支持它，因此在运行时加载它：

1. Remove the element from the XAMl, and instead place any container such as a Border:

   <Border x:Name="cefChromeContainer" />
   

2. in the Constructor code, after InitializeComponent();call, craete the browser element and place into the container. even better to declare the browser in the class scoop:

   CefSharp.Wpf.ChromiumWebBrowser browser = new CefSharp.Wpf.ChromiumWebBrowser();
   
   public MainWindow()
   {
       InitializeComponent();
       cefChromeContainer.Content = browser;
       browser.Address = "https://stackoverflow.com";
   }
   

1. 从 XAMl 中删除元素，并放置任何容器，例如 Border：

   <Border x:Name="cefChromeContainer" />
   

2. 在构造函数代码中，InitializeComponent();调用后，创建浏览器元素并放入容器中。甚至更好地在类 scoop 中声明浏览器：

   CefSharp.Wpf.ChromiumWebBrowser browser = new CefSharp.Wpf.ChromiumWebBrowser();
   
   public MainWindow()
   {
       InitializeComponent();
       cefChromeContainer.Content = browser;
       browser.Address = "https://stackoverflow.com";
   }

I had the same problem and i solve it changing configuration to from "debug" to "release" and using "x64" as platform.

我遇到了同样的问题，我解决了将配置从“调试”更改为“发布”并使用“ x64”作为平台的问题。

But it was not enought to change it from the solution menú, as i usually do. You need to go to visual studio main menú under "Compile > Configuration administration", as you can see in the following link from Microsoft:

但是，像我通常所做的那样，从解决方案菜单中更改它是不够的。您需要转到“编译>配置管理”下的visual studio主菜单，您可以在Microsoft的以下链接中看到：

https://docs.microsoft.com/es-es/visualstudio/ide/how-to-configure-projects-to-target-platforms?view=vs-2015&redirectedfrom=MSDN#Anchor_0

This solution was in fact in the Readme.txt file for cefsharp, as stated in the "Documentation" link provided by saschadin his answer: https://github.com/cefsharp/CefSharp/blob/cefsharp/69/NuGet/Readme.txt

这个解决方案实际上在 cefsharp 的 Readme.txt 文件中，如saschad在他的回答中提供的“文档”链接中所述：https: //github.com/cefsharp/CefSharp/blob/cefsharp/69/NuGet/Readme 。文本

There you can read it:

在那里你可以阅读它：

• For x86or x64set your solution target architecture tox86orx64`, just changing the project is currently not enough (See https://msdn.microsoft.com/en-us/library/ms185328.aspx#Anchor_0for details).

• 对于x86x64 set your solution target architecture tox86 orx64`，仅更改项目目前还不够（有关详细信息，请参阅 https://msdn.microsoft.com/en-us/library/ms185328.aspx#Anchor_0）。

Now I have it running like a charm :D

现在我让它像魅力一样运行：D

You can read in the (Documentation) of the NuGet package, it's also necessary to add an app.manifestto your Application.

您可以阅读NuGet 包的（文档），还需要app.manifest向您的应用程序添加一个。
