Developers can integrate WebView2 into their projects in several ways, as it supports C#, C++, and WinForms. This flexibility allows for various application types. The control is designed to be easy to use, with a familiar API for those experienced with web development.

WebView2 can share resources and functionality across platforms. Developers can create rich user experiences with the flexibility of web technologies and the effectiveness of native applications by embedding Edge-based content.

WebView2’s support for Windows applications, combined with its compatibility with Edge’s latest features, makes it a powerful tool for developers looking to create hybrid applications.

Compatibility Mode

Compatibility Mode provides a critical tool for developers and testers who need to ensure compatibility with legacy websites and older browser technologies. This allows testers to test how the website or application behaves when accessed by browsers with different user agent strings.

Testers can simulate older versions of Internet Explorer to identify potential issues and ensure a consistent user experience across various platforms. This is useful when working with legacy systems where maintaining compatibility with older technologies is essential.

Here’s how to enable Compatibility Mode in Microsoft Edge online:

  • Click the Developer Tools panel and select “Inspect”.
  • Locate the “Emulation” tab. If it’s not immediately visible, click the “…” menu to find it.
  • Testers can choose the desired browser version from the “User Agent String” dropdown. This allows testers to emulate specific versions of Internet Explorer.

Using Compatibility Mode, developers, and testers can ensure that legacy websites continue to function and identify compatibility issues with older browsers.

Vertical Tabs

Vertical Tabs offers an innovative way to manage and navigate through multiple open tabs. This feature is useful for developers and testers who often work with numerous browser tabs during testing and development.

Vertical Tabs displays all open tabs in a vertical sidebar on the browser window. This provides several benefits for users who need to manage a high volume of tabs:

  • Improved Visibility: With Vertical Tabs, testers can see the full title of each tab, reducing the need to hover over truncated tab titles to find the one tester needs. This clear view helps testers quickly locate and switch between tabs.
  • Efficient Navigation: Vertical Tabs make it easier to manage multiple tabs. testers can drag and drop tabs to reorder them, close tabs more efficiently, and even create tab groups for related projects or workflows.
  • Enhanced Workflow: By using Vertical Tabs, testers can increase productivity and improve the workflow. The vertical layout allows testers to view more tabs at once without cluttering the top of the browser.
  • Collapsible Sidebar: If testers need more screen space for web content, the Vertical Tabs sidebar can be collapsed to focus on the main content area.
  • Click the “Turn on vertical tabs” icon to activate vertical tabs. Once enabled, testers can customize the sidebar’s behavior to suit the workflow.

Microsoft Edge’s Collections feature organizes and saves groups’ web pages Testers can create and organize groups of related web pages, add notes, and even export data to Excel to provide an efficient way to keep track of the work.

Here’s how tester can make the most of Edge’s Collections:

  • Create Collections: Click on the Collections to create new collections. Give the collection a name that suits its purpose.
  • Add Webpages: The tester can start adding web pages to it. Simply drag a tab into the Collections pane, or click the “Add current page” button. This allows testers to gather all relevant resources in one place for easy access.
  • Add Notes: Collections let testers add notes to individual entries, providing context or additional information. This is useful for documenting testing scenarios, outlining development tasks, or adding commentary to shared resources.
  • Organize and Rearrange: A tester can rearrange items within a collection by dragging them into the desired order. This flexibility makes it easy to keep the collections organized, especially when managing multiple projects.
  • Share and Export: Collections can be shared for collaborative testing or development. testers can export collections to Excel or OneNote.

Edge’s Collections feature is a valuable tool for testers, developers, and anyone who needs to manage and organize web-based resources.
