+## Introduction
+
+This DevExpress WPF example displays code in a custom `CodeEditor` control. The control wraps the [Monaco Editor](https://microsoft.github.io/monaco-editor/), the editor used in Visual Studio Code. Monaco Editor supports modern code editing features such as syntax highlighting, region folding, a minimap, theming, and custom language support. Since **Monaco Editor** is a web control, the WPF wrapper uses [Microsoft WebView2](https://learn.microsoft.com/en-us/microsoft-edge/webview2/) to display it.
+
+
+
+
+
+The `CodeEditor` implementation uses the following helper classes:
+
+- `ThemeBehavior` - integrates Monaco with DevExpress themes.
+- `CodeEditorService` - a lightweight service for scenarios where direct interaction with the control is not sufficient.
+
+The control is designed as a **state-driven wrapper**: WPF owns the editor state through dependency properties, and Monaco Editor reflects that state and propagates changes back to WPF in an MVVM-friendly way.
+
+
+## Prerequisites
+
+- DevExpress WPF v26.1 (or newer compatible version)
+- Monaco Editor v0.55.1 (the control is built and validated against this specific release)
+- .NET version compatible with DevExpress WPF version you use: [WPF Controls → Prerequisites → .NET / .NET Core](https://docs.devexpress.com/WPF/8091/prerequisites#netnet-core)
+- Windows with [Microsoft Edge WebView2 Runtime](https://learn.microsoft.com/en-us/microsoft-edge/webview2/concepts/distribution)
+
+> The `CodeEditor` project must be compiled against the same DevExpress WPF version that is used in the consuming application.
+
+## Quick Start
+
+### 1. Add the `CodeEditor` project
+
+Add the `CodeEditor` project to your solution and reference it from your WPF application:
+
+- Add existing project → `CodeEditor`
+- Add project reference from your WPF app
+- Ensure DevExpress WPF and WebView2 dependencies are resolved
+
+### 2. Declare the XML namespace
+
+```xml
+<Window
+    x:Class="YourApp.MainWindow"
+    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
+    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
+    xmlns:ce="clr-namespace:CodeEditor;assembly=CodeEditor">
+
+    <Grid>
+        <ce:CodeEditor
+            Text="{Binding Code, Mode=TwoWay}"
+            EditorLanguage="csharp"
+            ThemeName="vs-dark" />
+    </Grid>
+
+</Window>
+```
+
+### 3. Create a ViewModel
+
+```csharp
+using DevExpress.Mvvm;
+
+public class MainViewModel : BindableBase
+{
+    private string _code = @"using System;
+
+class Program
+{
+    static void Main()
+    {
+        Console.WriteLine(""Hello, Monaco!"");
+    }
+}";
+
+    public string Code
+    {
+        get => _code;
+        set => SetProperty(ref _code, value);
+    }
+}
+```
+
+Set the `DataContext` of the window to an instance of `MainViewModel`.
+
+The editor content is automatically synchronized with the bound property.
+
+> **Note:**  
+> `CodeEditor` does not automatically track DevExpress theme changes.  
+> To synchronize Monaco with the active DevExpress theme, use `ThemeBehavior`.
+
+## Theming
+
+`CodeEditor` supports built-in Monaco themes, DevExpress theme integration, and custom theme registration.
+
+### Built-in Monaco Themes
+
+You can use standard Monaco themes:
+
+```csharp
+editor.ThemeName = "vs";
+editor.ThemeName = "vs-dark";
+editor.ThemeName = "hc-black";
+```
+
+
+
+### DevExpress Theme Integration
+
+
+
+To synchronize a Monaco Editor with the active DevExpress theme, attach a `ThemeBehavior`:
+
+```xml
+xmlns:ce="clr-namespace:CodeEditor;assembly=CodeEditor"
+xmlns:cet="clr-namespace:CodeEditor.Theming;assembly=CodeEditor"
+xmlns:dxmvvm="http://schemas.devexpress.com/winfx/2008/xaml/mvvm"
+
+...
+
+<ce:CodeEditor
+    Text="{Binding Code}"
+    EditorLanguage="csharp">
+
+    <dxmvvm:Interaction.Behaviors>
+        <cet:ThemeBehavior ApplyDevExpressColors="True" />
+    </dxmvvm:Interaction.Behaviors>
+
+</ce:CodeEditor>
+```
+
+`ThemeBehavior` synchronizes DevExpress themes and Monaco Editor appearance in the following manner:
+
+- Detects the current DevExpress theme at startup and each time the theme changes
+- Resolves Light / Dark / High Contrast base
+- Registers and applies a corresponding Monaco theme
+- Optionally maps DevExpress palette colors to Monaco color keys via the `ApplyDevExpressColors` property
+
+
+
+### Custom Themes
+
+You can register a custom Monaco theme programmatically:
+
+```csharp
+var theme = new MonacoTheme
+{
+    Name = "my-theme",
+    Base = MonacoThemeBase.Dark,
+    Colors = new Dictionary<string, Color>
+    {
+        ["editor.background"] = Color.FromRgb(30, 30, 30),
+        ["editor.foreground"] = Color.FromRgb(220, 220, 220)
+    }
+};
+
+editor.RegisterTheme(theme);
+editor.ThemeName = "my-theme";
+```
+
+For a complete list of commonly used Monaco theme color keys, see the official VS Code theme color reference (Monaco uses the same keys): [Theme Color](https://code.visualstudio.com/api/references/theme-color).
+
+### Rules
+
+In addition to UI colors, Monaco themes support token-level styling via `Rules`.
+
+Rules define how the editor renders specific token types such as `keyword`, `comment`, `string`, and others.
+
+You can use `Rules` to override the appearance of existing token types or to define styling for custom tokens introduced by a custom language definition.
+
+```csharp
+var theme = new MonacoTheme
+{
+    Name = "my-theme",
+    Base = MonacoThemeBase.Dark,
+    Rules = new[]
+    {
+        new MonacoThemeRule
+        {
+            Token = "keyword",
+            Foreground = Color.FromRgb(86, 156, 214),
+            FontStyle = MonacoFontStyle.Bold
+        },
+        new MonacoThemeRule
+        {
+            Token = "comment",
+            Foreground = Color.FromRgb(106, 153, 85),
+            FontStyle = MonacoFontStyle.Italic
+        }
+    }
+};
+```
+
+`Rules` is an init-only property and must be provided during theme initialization.
+
+If you use `ThemeBehavior`, token styling can also be supplied through its `Rules` property, and it allows rule customization alongside DevExpress theme integration.
+
+## Languages
+
+`CodeEditor` supports both built-in Monaco languages and custom language registration.
+
+### Built-in Languages
+
+To use a built-in Monaco language, specify the `EditorLanguage` property:
+
+```csharp
+editor.EditorLanguage = "csharp";
+editor.EditorLanguage = "javascript";
+editor.EditorLanguage = "json";
+```
+
+The value must match a language ID supported by Monaco Editor.
+
+### Custom Languages
+
+You can register custom languages using `LanguageDescriptor`:
+
+```csharp
+var language = new LanguageDescriptor
+{
+    Id = "mylang",
+
+    Monarch = @"{
+        tokenizer: {
+            root: [
+                [/\b(if|else|while)\b/, 'keyword'],
+                [/\/\/.*$/, 'comment'],
+                [/"".*?""/, 'string'],
+                [/\d+/, 'number']
+            ]
+        }
+    }",
+
+    Configuration = @"{
+        comments: {
+            lineComment: '//'
+        },
+        brackets: [
+            ['{', '}'],
+            ['[', ']'],
+            ['(', ')']
+        ]
+    }"
+};
+
+editor.RegisterLanguage(language);
+editor.EditorLanguage = "mylang";
+```
+
+### Monarch Definition
+
+The `Monarch` property defines syntax highlighting rules.
+
+The property must contain a valid Monaco Monarch tokenizer definition specified as a JavaScript object literal.
+
+All standard Monarch features are supported:
+
+- Multiple states
+- Nested states
+- Regular expressions
+- Rule objects
+- Includes and state transitions
+
+Refer to the following help topic for additional information: [Monarch Documentation](https://microsoft.github.io/monaco-editor/monarch.html)
+
+### Language Configuration
+
+The optional `Configuration` property defines editor behavior attributes such as:
+
+- Line and block comments
+- Brackets
+- Auto-closing pairs
+- Surrounding pairs
+
+The configuration must also be provided as a JavaScript object literal.
+
+For additional information, refer to the following help topic: [Language Configuration Guide](https://code.visualstudio.com/api/language-extensions/language-configuration-guide)
