To replace the WebBrowser control with the ChromiumWebBrowser control in your .NET Desktop Application, you'll need to perform the following steps:

Install CefSharp NuGet Package: If you haven't already, you'll need to install the CefSharp NuGet package, which provides the ChromiumWebBrowser control. You can install it via NuGet Package Manager or via the Package Manager Console with the following command:
```
Install-Package CefSharp.WinForms
```

Replace WebBrowser Control: In your Form1.Designer.cs file, replace the declaration and initialization of the WebBrowser control with ChromiumWebBrowser. Here's how your code should look after the replacement:

using CefSharp;
using CefSharp.WinForms;

// Replace:
// private System.Windows.Forms.WebBrowser webBrowse;
// with:
private ChromiumWebBrowser chromiumWebBrowser;

And replace the initialization code as follows:

// Replace:
// this.webBrowse = new System.Windows.Forms.WebBrowser();
// with:
this.chromiumWebBrowser = new ChromiumWebBrowser();

Adjust Event Handlers: Since ChromiumWebBrowser is a different control, you may need to adjust event handler subscriptions. The events you're handling (DocumentCompleted, Navigated) may have equivalent events in ChromiumWebBrowser, but with different names or signatures. Adjust these event subscriptions accordingly.
Remove Unused Code: After replacing the WebBrowser control with ChromiumWebBrowser, you may have some unused code related to the old WebBrowser control. Make sure to remove or refactor any such code to ensure your application remains clean and efficient.
By following these steps, you should be able to replace the WebBrowser control with the ChromiumWebBrowser control in your .NET Desktop Application and utilize the Chromium-based browser functionality.
Build and Test: After making these changes, rebuild your application and test to ensure that the ChromiumWebBrowser control is functioning as expected and that all event handlers are correctly wired up.
