+# WebView2 SDK Setup for KryptonWebView2
+
+## Overview
+
+The KryptonWebView2 control requires the Microsoft WebView2 SDK assemblies to be available for compilation. This document explains how to set up the WebView2 SDK without using NuGet dependencies.
+
+**Quick Start**: Run `run.cmd` and select option 7 "WebView2 SDK Tools" → option 1 "Setup WebView2 SDK" for automated setup.
+
+**Latest Version**: The setup automatically detects and uses the latest stable WebView2 SDK version from NuGet.
+
+## Setup Options
+
+### Option 1: Manual Download (Recommended)
+
+1. **Download WebView2 SDK**
+   - Visit: https://developer.microsoft.com/en-us/microsoft-edge/webview2/
+   - Download the latest WebView2 SDK
+   - Extract the downloaded package
+
+2. **Copy Required Assemblies**
+   - Create a `WebView2SDK` folder at the repository root (same level as `Source` folder)
+   - Copy the following files from the extracted SDK to `WebView2SDK`:
+     ```
+     WebView2SDK/
+     ├── Microsoft.Web.WebView2.Core.dll
+     ├── Microsoft.Web.WebView2.WinForms.dll
+     └── WebView2Loader.dll
+     ```
+
+3. **Build the Solution**
+   - Rebuild the entire solution
+   - The KryptonWebView2 control should now compile successfully
+
+### Option 2: Using NuGet (Temporary)
+
+If you want to quickly get the assemblies without manual download:
+
+1. **Install NuGet Package**
+   ```cmd
+   dotnet add package Microsoft.Web.WebView2
+   ```
+
+2. **Copy Assemblies**
+   - Find the NuGet packages folder (usually `%USERPROFILE%\.nuget\packages\`)
+   - Navigate to the latest version folder (e.g., `microsoft.web.webview2\1.0.3485.44\lib\net45\`)
+   - Copy the required DLLs to the `WebView2SDK` folder
+   - Remove the NuGet package reference if desired
+
+3. **Clean Up**
+   ```cmd
+   dotnet remove package Microsoft.Web.WebView2
+   ```
+
+### Option 3: Using Setup Script (Recommended)
+
+#### Method A: Through Build System Menu
+1. **Run the Build System**
+   ```cmd
+   run.cmd
+   ```
+2. **Select Option 7**: "WebView2 SDK Tools"
+3. **Select Option 1**: "Setup WebView2 SDK"
+4. **Follow the automated process**
+
+#### Method B: Direct Script Execution
+Run the provided setup script directly:
+```cmd
+Setup-WebView2SDK.cmd
+```
+
+Both methods will:
+- Check if WebView2 SDK is already installed
+- Automatically detect the latest stable WebView2 SDK version
+- Download and install WebView2 SDK via NuGet (if needed)
+- Copy required assemblies to the WebView2SDK directory
+- Update project file with the latest version information
+- Clean up temporary NuGet references
+- Provide clear feedback on the setup status
+
+### Option 4: Update to Latest Version
+
+If you already have WebView2 SDK installed and want to update to the latest version:
+
+#### Method A: Through Build System Menu
+1. **Run the Build System**
+   ```cmd
+   run.cmd
+   ```
+2. **Select Option 7**: "WebView2 SDK Tools"
+3. **Select Option 2**: "Update WebView2 SDK"
+4. **Follow the automated update process**
+
+#### Method B: Direct Script Execution
+Run the update script directly:
+```cmd
+Scripts\Update-WebView2SDK.cmd
+```
+
+Both methods will:
+- Detect the latest stable WebView2 SDK version
+- Download the latest assemblies
+- Update the WebView2SDK directory
+- Update project file references
+- Preserve your existing setup
+
+## File Structure After Setup
+
+Your repository should look like this:
+```
+Standard-Toolkit/
+├── Source/
+│   └── Krypton Components/
+│       └── Krypton.Toolkit/
+│           └── Controls Toolkit/
+│               └── KryptonWebView2.cs
+├── Scripts/
+│   ├── Setup-WebView2SDK.cmd
+│   ├── Update-WebView2SDK.cmd
+│   ├── Get-LatestWebView2Version.ps1
+│   └── Update-WebView2ProjectVersion.ps1
+├── WebView2SDK/                    ← Created by setup script
+│   ├── Microsoft.Web.WebView2.Core.dll
+│   ├── Microsoft.Web.WebView2.WinForms.dll
+│   └── WebView2Loader.dll
+└── run.cmd                         ← Updated with WebView2 SDK Tools submenu
+```
+
+## Verification
+
+After setup, verify that the KryptonWebView2 control compiles:
+
+1. **Build the Solution**
+   ```cmd
+   dotnet build "Source/Krypton Components/Krypton Toolkit Suite 2022 - VS2022.sln"
+   ```
+
+2. **Check for Errors**
+   - No compilation errors related to WebView2 types
+   - KryptonWebView2 appears in the toolbox
+   - Test form compiles successfully
+
+## Troubleshooting
+
+### "WebView2 types not found" Error
+- Ensure the WebView2SDK folder exists at the repository root
+- Verify all three DLL files are present in WebView2SDK
+- Check that the project file references point to the correct paths
+- Rebuild the solution completely
+
+### Assembly Loading Errors
+- Ensure the DLLs are the correct architecture (AnyCPU or x64)
+- Check that the DLLs are not corrupted
+- Verify the file permissions allow reading
+
+### Designer Issues
+- Reset the Visual Studio toolbox
+- Close and reopen Visual Studio
+- Ensure the control compiles without errors first
+
+## Runtime Requirements
+
+Remember that end users need the WebView2 Runtime installed:
+
+- **Evergreen Distribution**: Users install from Microsoft's website
+- **Fixed Version**: Bundle with your application
+- **Download**: https://developer.microsoft.com/en-us/microsoft-edge/webview2/
+
+## Support
+
+If you encounter issues:
+
+1. Check the WebView2 documentation: https://docs.microsoft.com/en-us/microsoft-edge/webview2/
+2. Verify your setup matches the requirements
+3. Test with the provided KryptonWebView2Test form
+4. Report issues to the Krypton Toolkit repository
+
+## Notes
+
+- The WebView2SDK folder should be added to `.gitignore` if you don't want to commit the assemblies
+- The assemblies are referenced with `Private=False` so they won't be copied to output
+- This setup allows the control to compile without NuGet dependencies
+- Runtime WebView2 functionality requires the WebView2 Runtime to be installed on target systems
