While installing this update, one might encounter an issue that prevents or blocks the installation of this update. The following table lists possible blocking issues and provides respective resolutions.


Resolution: This update is not supported on Windows 10 Fall Creators update (Version 1709) or Server 2016 Version 1709 and the changes in this update will be available in an upcoming Cumulative Update for Windows 10 Fall Creators update (Version 1709) and Server 2016 Version 1709.


The installed security updates and hotfixes for each version of the .NET Framework installed on a computer are listed in the Windows registry. You can use the Registry Editor (regedit.exe) program to view this information.


In the Registry Editor, the .NET Framework versions and installed updates for each version are stored in different subkeys. For information about detecting the installed version numbers, see How to: Determine which .NET Framework versions are installed.


This security update addresses a vulnerability where restricted mode is triggered for the parsing of XPS files, preventing gadget chains which could allow remote code execution on an affected system. For more information please see CVE-2022-41089.


Note: Customers that rely on Windows Update and Windows Server Update Services will automatically receive the .NET Framework version-specific updates. Advanced system administrators can also take use of the below direct Microsoft Update Catalog download links to .NET Framework-specific updates. Before applying these updates, please ensure that you carefully review the .NET Framework version applicability, to ensure that you only install updates on systems where they apply.


A framework update comes with a lot of good things like the removal of bugs discovered in the previous version(s), patch security flaws, performance improvements, and new features that make the development process easier.


Installing the latest Visual Studio that comes with the latest .NET Framework and .NET Core versions is not enough, some changes need to be done to the projects as well to support the latest features that come with the framework.


Before deploying the updated application to a specific machine, you have to be sure that the latest .NET Framework is installed there too and the application will run as it was running on your development machine. Microsoft created an article solely for this purpose: How to: Determine which .NET Framework versions are installed. If the installed version is an older one, you have to download and install the desired version (in our case .NET Framework 4.7.2) from here. Once this step is completed you can continue to the next step.


Updating your project solution to the latest framework version takes some time, but it can save time and money in the long run. And this because the latest framework updates include security patches for the holes that hackers and malware know to look for.


You can get the update via the Microsoft Update Catalog. For Windows 10, NET Framework 4.8 updates are available via Windows Update, Windows Server Update Services, Microsoft Update Catalog. Updates for other versions of .NET Framework are part of the Windows 10 Monthly Cumulative Update.


The .Net Framework is a software framework from Microsoft that provides a programming model for building and running applications. The framework is designed to be used by developers who want to create applications that can run on the Windows platform.Microsoft has released several versions of the .Net Framework since its initial release in 2002. The most current (and last) version is .Net Framework 4.8. However, Microsoft is continuing to provide support for older versions, including 4.6.2, 4.7, 4.7.1, and 4.7.2. Any version older than 4.6.2 is no longer being supported by Microsoft, which means that there will be no more security updates or technical support for these past versions.For developers, it is important to know which versions of the .Net Framework are still supported by Microsoft. Monitoring the support end dates will give you a chance to plan for migration to a newer version (if necessary) before your application becomes unsupported.


Recent Microsoft cumulative updates result in a crash for ArcGIS Pro 2.8.x and 2.9.x users when changing symbology. This post provides additional information about the crash and what Esri recommends that customers do.


For compatibility reasons I want to keep the current .NET Framework version (which is 4.7, the latest version) and stop automatic/silent updates in the future from Windows Update or WSUS only for .NET Framework version while allowing all other system/security updates on a Windows Server 2008 or 2012.I have found answers for how to prevent updating to a certain .NET Framework version or how to hide the update from the list of updates in Windows Update after the update is already available, but this is not what I want.What I'm interested is preventing updating from a .NET Framework version when we don't know if, when and to what version an upgrade will be available. E.g. the latest .NET Framework available is version 4.7. Future versions could be 4.7.1, 4.7.2, 4.8 or 4.9 but we don't know yet. How can one prevent these future updates from being installed by Windows Update or WSUS on a Windows Server 2008/2012?


I think this is a very sensible question, and I'm a bit surprised that the whole internet seems to be trusting Microsoft not to break their stuff (at least in the context of automatic web server .NET Runtime updates).


But for a critical application on a Production server, there is a definite risk to automatically rolling out version upgrades to the underlying code without first testing them in a Staging environment. Although rare, there are known instances of existing applications being broken by Microsoft's in-place Windows Updates. (This is also a risk for updates generally, including security updates.)


If your organization uses an update management solution, such as Microsoft WSUS or System Center Configuration Manager, those tools can be used to selectively approve or defer your updates individually.


(Less reliable) Recent .NET Framework version updates have been rolled out as Recommended updates. If you disable Recommended updates that might partially mitigate the risk that a future .NET Framework version update would be rolled out automatically without testing.


Updating Dot Net version on Windows 10 or Windows 11 PCs are going to be a bit challenging. There are many options to update the .Net version on the client-side. The challenging part of the DotNet update is the repair and fix update issues of the .Net Framework.


As you can see in the warning message, A later version of SCCM will require .NET version 4.8, and I guess this is the SCCM 2111 version, which will get released by the end of Nov 2021. To minimize disruption, before you run Configuration Manager setup, update .NET and restart the system.


After the restart of the servers, I could see the version; the .NET version got updated. I thought even Management Insights would be happy now with the versions of the .NET. But, Management Insights is not satisfied with the .NET yet.


I will go on and troubleshoot this issue. I will update the post once I get the resolution on this point. I added another section to the blog post where I will discuss about troubleshooting of the issue and resolution.


The Dot NET 4.8 Prerequisite check warning will also appear while installing the SCCM 2111 update and even SCCM 2203. Microsoft recommends installing the .NET version 4.8 on all the SCCM servers and components that use .NET framework.


.NET 4.8 or higher is not installed on Server indicates that a lower version of Dot Net framework is installed for SCCM. Based on the above warning, it means that Microsoft recommends installing the .NET version 4.8 for the Configuration Manager.


The upcoming versions of Configuration Manager such as version 2203 will require .NET version 4.8. To minimize disruption, before you run Configuration Manager setup, update .NET to version 4.8 and restart the system.


Note: If you are using Windows 11, all the Windows 11 versions comes preinstalled with .NET Framework 4.8. The Windows Server 2022 operating system also comes with a preinstalled version of the .NET framework 4.8.

The .NET Framework family also includes two versions for mobile or embedded device use. A reduced version of the framework, the .NET Compact Framework, is available on Windows CE platforms, including Windows Mobile devices such as smartphones. Additionally, the .NET Micro Framework is targeted at severely resource-constrained devices. 2ff7e9595c
