<p>how i solve this error</p>

<p>The type or namespace name 'ThemeInfo' could not be found (are you missing a using directive or an assembly reference?) </p>

<p>AssemblyInfo.cs</p>

<pre><code>using System.Reflection;
using System.Resources;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;
using System.Windows;

// General Information about an assembly is controlled through the following 
// set of attributes. Change these attribute values to modify the information

[assembly: AssemblyTitle("Emgu.CV.WPF")]
[assembly: AssemblyDescription("")]

// Setting ComVisible to false makes the types in this assembly not visible 
// to COM components.  If you need to access a type in this assembly from 
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(false)]

//In order to begin building localizable applications, set 
//&lt;UICulture&gt;CultureYouAreCodingWith&lt;/UICulture&gt; in your .csproj file
//inside a &lt;PropertyGroup&gt;.  For example, if you are using US english
//in your source files, set the &lt;UICulture&gt; to en-US.  Then uncomment
//the NeutralResourceLanguage attribute below.  Update the "en-US" in
//the line below to match the UICulture setting in the project file.

//[assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallbackLocation.Satellite)]


[assembly: ThemeInfo(
    ResourceDictionaryLocation.None, //where theme specific resource dictionaries are located
    //(used if a resource is not found in the page, 
    // or application resource dictionaries)
    ResourceDictionaryLocation.SourceAssembly //where the generic resource dictionary is located
    //(used if a resource is not found in the page,
