The name ChromiumWebBrowser does not exist in the namespace “clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf”

问题

I had followed this link to implement CefSharp applicaton.

But I have stuck while coding MainWindow.xaml.

Blend for VS 2015 said,

The name ChromiumWebBrowser does not exist in the namespace "clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf"

But I'm installed CefSharp.Common and CefSharp.Wpf v51.0.0, cef.redist.x64 and cef.redist.x86 v3.2704.1432 with NuGet Package Manager.

I'm new on developing C# so I don't know how to solve this problem. Please help me to solve this error.

This is my MainWindow.xaml

<Window x:Class="StocktalkBrowser.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:StocktalkBrowser"
        xmlns:cefSharp="clr-namespace:CefSharp.Wpf;assembly=CefSharp.Wpf"
        mc:Ignorable="d"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <cefSharp:ChromiumWebBrowser Grid.Row="0"  Address="https://github.com/cefsharp/CefSharp/wiki/Frequently-asked-questions" />
    </Grid>
</Window>

回答1:

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

Can be ignored.

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

No errors when compiling

And the program starts up. No problem

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.

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.

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

Remove the element from the XAMl, and instead place any container such as a Border:
```
<Border x:Name="cefChromeContainer" />
```

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";
}

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