Upcoming Updates for .NET Framework 4.8

The .NET Framework 4.8 product release is now available. The .NET Framework 4.8 product will receive updates on the same cadence and the usual channels (Windows Update, WSUS, Catalog) as all .NET Framework and Windows cumulative updates. For Windows 10, .NET Framework 4.8 updates will now be delivered as independent updates, alongside the Windows cumulative updates.  In this post, I explain how updates to .NET Framework 4.8 are delivered so you are ready for them.

 

What is new about .NET Framework 4.8 updates?

Updates for .NET Framework 4.8 on Windows 10 versions 1607, 1703, 1709, 1803 and Server 2016 will now be delivered independently and side by side with Windows cumulative updates. The way we update .NET Framework in Windows 10 version 1809 and Server 2019 is not changing and is described below.

 

What does not change?

Updates to .NET Framework 4.8 on Windows 8.1, Server 2012 R2, Server 2012, Windows 7 SP1, and Server 2008 R2 SP1 will continue to be delivered outside of the Windows cumulative update through the existing .NET Framework updates.

The update for .NET Framework 4.8 will be included into the .NET Framework Rollup, for each operating system. Likewise, for Windows 10 version 1809, Server 2019, and future releases, .NET Framework 4.8 will be updated as part of the existing .NET Framework updates.

The delivery of updates to all previous versions of .NET Framework (i.e. .NET 4.7.2, 4.7.1, 4.7, 4.6.2, 4.6.1, 4.6, 4.5.2, and 3.5) across all supported operating systems does not change. There is no change in the way you acquire or install these updates.

 

What should I expect?

You can expect the following experiences:

Windows update customers:

  • If you rely on Windows Update to keep your machine up to date and have automatic updates enabled, you will not notice any difference.  Updates for both Windows and the .NET Framework 4.8 and previous versions will be silently installed, and as usual you may be prompted for a reboot after installation.
  • If you manage Windows Update manually, you will notice that updates for .NET Framework 4.8 will be available alongside Windows cumulative updates. Please continue to apply the latest updates to keep your system up to date.

System and IT Administrators:

  • System administrators relying on Windows Server Update Services (WSUS) and similar update management applications will observe a new update for .NET Framework 4.8 when checking for updates applicable to Windows 10 versions 1607, 1703, 1709, 1803 and Server 2016. For all other operating systems the update for .NET Framework 4.8 will continue to be included into the existing .NET Framework update.
  • The Classifications for Updates for .NET Framework 4.8 remain the same as for the Cumulative Update for Windows and continue to show under “WindowsProducts. Updates that deliver new Security content will have the “Security Updates” classification and updates that solely carry new quality updates will either have the “Updates” or “Critical Updates” classification, depending on their criticality.
  • System administrators that rely on the Microsoft Update Catalog will be able to access updates for .NET Framework 4.8 by searching for each releases’ Knowledge Based (KB) update number.
  • You can use the update title to filter between the Windows Cumulative updates and .NET Framework updates. All other update artifacts remain the same.

 

.NET Update release vehicles across operating systems

Updates for .NET Framework 4.8 are delivered as described in the below table.

Frequently Asked Questions (FAQ)

  • What is the .NET Framework 4.8 product?

More information about the .NET Framework 4.8 product here: https://devblogs.microsoft.com/dotnet/announcing-the-net-framework-4-8/

  • If I don’t upgrade to .NET Framework 4.8 will anything change for how I receive Windows or .NET updates?

No. Updates for previous versions of .NET Framework and for Windows operating systems components remain the same.

  • Why are updates to all .NET Framework versions not delivered through a consistent single rollup vehicle across operating systems?

We aim to keep the .NET Framework update experience as smooth and consistent as possible across supported operating systems. Specifically for Windows 10 versions 1607, 1703, 1709, 1803 and Server 2016 systems (where .NET rollup updates did not exist), we chose to introduce the least possible change, and leave the experience untouched for updating previous versions of .NET Framework (i.e. .NET 4.7.2 and below). For .NET Framework 4.8 we are able to offer the same agility and flexibility as described in our recent post announcing cumulative updates for .NET Framework for Windows 10 October 2018 update across all operating systems.

  • I am an IT Administrator managing updates for my organization, how do I ensure that my deployments include all existing versions of .NET Framework?

As noted above, continue to rely on the same mechanisms for Windows and .NET Framework updates. Ensure that within your WSUS, SCCM or similar environment, you select updates that correspond to the “WindowsProduct, and continue to rely on the Classifications categories to select all applicable updates that align with your organization’s update criteria for Security and non-security content. This will ensure you continue to receive updates for all .NET Framework versions.

  • I rely on downloading updates from the Microsoft Update Catalog to support my organization’s internet-disconnected scenarios. Do I need to do anything differently to update systems with .NET Framework 4.8?

Whether you depend directly on the Microsoft Update Catalog website or import updates from Catalog into your managed environments (e.g. WSUS, or SCCM), please continue to rely on the Knowledge Base(KB) number lookup functionality to access .NET Framework updates. For operating systems where .NET Framework rollup updates existing already, continue to search and download the KBs for each target operating system. On operating systems where .NET Framework rollups did not previously exist (i.e. Windows 10 versions 1607, 1703, 1709, 1803 and Server 2016), search for the corresponding KB numbers that are specific to updates for .NET Framework 4.8.

  • Does anything change about the way updates to .NET Framework 3.5 get delivered once I upgrade to .NET Framework 4.8?

The .NET Framework 3.5 will continue to be delivered the same way (refer to the “.NET updates across Windows versions” table above).

For Windows 8.1 and previous operating systems, .NET Framework 3.5 updates are included in the .NET Framework Rollup.

For Windows 10 versions 1507, 1607, Server 2016, 1703, 1709, 1803, .NET Framework 3.5 updates are included in the Windows Cumulative updates.

For Windows 10 version 1809, Server 2019 and future versions, .NET Framework 3.5 updates are included in the .NET Framework Cumulative Update.

Please continue to install both .NET Framework 4.8 and Windows cumulative updates to be up to date for all .NET Framework versions.

Does .NET Framework 4.8 have a KB number? I didn't see it for download in the Microsoft Update Catalog.

Thanks for detailing how the update will be delivered, so independently from the Windows Cumulative Update. It is a first step to move the .NET Framework out of the Windows OS as it was until 4.5? Or does .NET Framework remains a first class component of the Windows OS?This other page says .NET 4.8 will be part of Windows 10 May 2019: https://docs.microsoft.com/en-us/dotnet/framework/get-started/system-requirements The real point behind all this is about the product lifecyle!By the way, please update the FAQ with .NET Framework 4.8: https://support.microsoft.com/en-us/help/17455/lifecycle-faq-net-framework With the recent announment of .NET 5 and beyond, and 4.8.x being the last full .NET Framework, the big question is: when will be the end of life of .NET Framework 4.8? Obvioulsy too early and risky to give a clear answer. But we can already get some ideas looking in the past: the FAQ linked above says the .NET 3.5 SP1 is supported until EOF of Windows 1809, so until 2028. 3.5 came out in 2008, so 20 years of support, not bad.So should we expect EOF of 4.8 in the mid/end 2030s? Please try to have a better communication this time by giving a clear timeframe to all your customers. Giving a EOF decades in advance will be much appreciated from all the entreprise level project, especially if .NET 4.8 marks the EOF of WCF. It is fine that a product has an EOF. Having a clear and foreseeable communication is just a better way to sell it.In the recent history, take Silverlight or the WindowsPhone/WindowsMobile, I think the main critics came out from unclear EOF or customers not clearly understanding what product lifecycle means! Silverlight version 5 is supported until 2021 under IE11, so customers had time to update their product. Windows Mobile had particular bad communcation time (especially with the w10m upgrade of wp8), but looking back at what has been done, each Lumia phone got 4 full years of support, which is way better than any Android phone! If Microsoft had defined the 4 years of life for every device since the beginning, it would have been much better for all customers. So please think about that for the .NET Framework 4.8! Or more generally, put your marketing folks on explaining what a product life means! Windows 7 EOF in Jan 2020 is starting to hit the news, ad did XP in 2014. But these Windows had a much longer lifecycle than any Apple or Google product!Now Microsoft is embracing the agile and continuous delivery approach, for good and bad, making life of decision's maker harder: .NET 5, 6 or 8 will be surely EOF before 4.8...
