.NET Framework January 2024 Cumulative Update Preview
Today, we are releasing the January 2024 Cumulative Update Preview Updates for .NET Framework.
Quality and Reliability
This release contains the following quality and reliability improvements.
ASP.NET
- Addresses an issue with “System.ArgumentException: Illegal characters in path” in some ASP.Net MVC requests.
.NET Libraries
- Addresses an issue where version of the OSS zlib library is out of date.
Getting the Update
The Cumulative Update Preview is available via Windows Update and Microsoft Update Catalog.
Customers using Windows 11, version 22H2 and Windows 11, version 23H2, you will now find .NET Framework updates on the Settings > Windows Update > Advanced options > Optional updates page.
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.
The following table is for Windows 10+ versions.
| Product Version | Cumulative Update | |
|---|---|---|
| Windows 11, version 23H2 | ||
| .NET Framework 3.5, 4.8.1 | Catalog | 5034467 |
| Windows 11, version 22H2 | ||
| .NET Framework 3.5, 4.8.1 | Catalog | 5034467 |
| Windows 10, version 22H2 | 5034582 | |
| .NET Framework 3.5, 4.8 | Catalog | 5034468 |
| .NET Framework 3.5, 4.8.1 | Catalog | 5034466 |
The operating system row lists a KB which will be used for update offering purposes. When the operating system KB is offered, the applicability logic will determine the specific .NET Framework update(s) will be installed. Updates for individual .NET Framework versions will be installed based on the version of .NET Framework that is already present on the device. Because of this the operating system KB is not expected to be listed as installed updates on the device. The expected update to be installed are the .NET Framework specific version updates listed in the table above.
