What is the current level of support Microsoft will provide for Silverlight?

For security reasons new builds of Microsoft Office for Microsoft 365 on Windows block activation of Flash, Silverlight, and Shockwave controls. Most users won't be impacted, but for some users this may cause one of the following issues.

Microsoft will provide technical help for customers using versions of Silverlight 5 only. Paid technical help is available to customers requiring support with issues beyond install and upgrade. Microsoft will continue to ship updates to the Silverlight 5 Developer Runtime for supported browser versions given that their extensibility model supports plug-ins; this includes updates for security vulnerabilities as determined by the Microsoft Security Response Center (MSRC).

Silverlight 5 will support the browser versions listed on the system requirements page through October 12, 2021, or though the lifecycle of the underlying browsers, whichever is shorter. The support page will be updated to reflect compatibility with newer browsers and operating system versions.

Windows 7 will reach its end of support date on January 14, 2020. Will Silverlight be supported as part of the Extended Security Update (ESU) program available for Windows 7 customers?

Silverlight’s lifecycle policy is independent from the Windows 7 policy. After January 14, 2020, customers using Silverlight on Windows 7 will no longer be supported and will no longer receive automatic security updates.

What happens on October 12, 2021? Will existing applications stop working?

Microsoft is not planning to take any specific action to terminate Silverlight applications. After this date, however, Silverlight will be in an unsupported state and will not receive any future quality or security updates.

Will companies be legally allowed to continue to run Silverlight assets after October 12, 2021? What happens to the license to use Silverlight after October 12, 2021?

Silverlight’s license is a perpetual license and is not tied to the continuation of support. While support will be ending in October 2021, this date does not affect the license, which continues in effect for as long as the customer is using the software and complies with the terms of the license.

Can companies obtain a custom agreement to extend Microsoft support past 2021?

There are no plans for extending Silverlight support beyond the existing support dates listed here.

What will happen to the microsoft.com/silverlight website after October 12, 2021?

The microsoft.com/silverlight website will still be available. However, the Silverlight installer will no longer be available after the end of support date of October 12, 2021.

What is the recommended technology/development framework for customers who want to migrate applications from Silverlight?

There are various options for migrating applications from Silverlight. We recommend that you evaluate the requirements of the application that you are migrating and determine the technology that best suits the application in question:

• If your application is non-browser dependent and you’d like to migrate to a Windows Desktop application, we recommend you migrate your application to UWP or WPF on .NET Core.

• If your application is web-based, we recommend that you look into Blazor, which allows re-usability of .NET Silverlight code. Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code are written in C#, allowing you to share code and libraries.

Compatibility Add-on for Chrome or Firefox

There is a free browser extension called 'IE Tab' that runs Windows Internet Explorer (IE) components within a tab in Chrome or Firefox. This enables you to display web pages that use Silverlight (such as CTI Navigator Web) within your Chrome or Firefox browser, even if the browser itself does not correctly load Silverlight. The IE Tab also includes an 'Auto URL' filter and a Bookmarks feature that allow you to specify which URLs should always be loaded with IE Tab.

Even though it does not open the IE browser per se, IE Tab uses the IE Browser Control core engine. Therefore, to ensure full security when using IE Tab, the latest version of Internet Explorer should be installed on your computer and it should be kept up-to-date with the latest security patches from Microsoft.

You can read about and download IE Tab at www.ietab.net.
