Obsolescence review for Microsoft components

Aditya Shah 20

Dear Team,

Just following up on my earlier request regarding the SBOM compilation and the security/obsolescence review for some instruments.

To finalize compliance documentation and plan upgrades, please share the details for each production component:

Components:

XMLDiffPatch 1.0.8.28 Microsoft Corporation

For each component, please provide:

1. Lifecycle & Support

Official EOS/EOL dates
Link to vendor lifecycle/support policy

2. Current Supported Versions

3. Upgrade Guidance

Recommended upgrade path (target version and any intermediate steps)

If any item is tracked elsewhere, a link or pointer to the source is perfect.

Thank you,

Aditya Shah

Hi @Aditya Shah ,

Thanks for reaching out.

Regarding Microsoft XML Diff and Patch Tool (XMLDiffPatch 1.0.8.28), here’s what I can confirm for your compliance and obsolescence review:

Lifecycle & Support:

This package does not have a published Microsoft lifecycle entry (no official EOS/EOL dates). It was originally released around 2012 and has not been updated since. It is not listed under Microsoft’s supported products in the official Lifecycle Policy portal. Microsoft Lifecycle Policy (general reference): https://learn.microsoft.com/lifecycle/products/

Because there is no defined lifecycle or active maintenance, this component should be considered legacy and unsupported from a compliance standpoint.

Current Supported Versions:

There are no newer supported versions published by Microsoft. Version 1.0.8.28 is the only version available on NuGet, and it has not been updated in many years.

Upgrade Guidance:

There is no direct Microsoft-supported upgrade path for this package. The recommended approach would be:

Replace the dependency with a maintained XML diff library (for example, a modern fork or actively maintained alternative).
Alternatively, re-implement the required XML comparison logic using supported .NET libraries where feasible.

From a governance and SBOM perspective, the safest position is to classify this component as legacy with no active vendor support, and plan for replacement rather than upgrade-in-place.

Hope this helps! If my answer was helpful - kindly follow the instructions here so others with the same problem can benefit as well.

Hi @Jack Dang (WICLOUD CORPORATION)
Thankyou so much for the details could you please give the same obsolescence review for the below component as well and also confirm if the XML Diff patch tool and the below given tool has vulnerabilities or not.

Hi @Aditya Shah ,

Thanks for the follow-up.

For Resgen.exe (resgen 2.0.0.0):

Resgen is not a standalone product and does not have its own EOS/EOL. It ships with the .NET Framework, so its support status depends entirely on the .NET Framework version installed. If the framework version is supported (e.g., 4.8), the included Resgen tool is supported. If the framework is out of support, Resgen is effectively out of support as well.

Tool documentation: https://learn.microsoft.com/dotnet/framework/tools/resgen-exe-resource-file-generator

Lifecycle reference: https://learn.microsoft.com/lifecycle/products/

.NET Framework lifecycle details: https://learn.microsoft.com/lifecycle/products/microsoft-net-framework

Vulnerabilities:

Microsoft XML Diff and Patch Tool - No specific published CVEs (Microsoft Security Update Guide: https://msrc.microsoft.com/update-guide), but it is old and not actively maintained, so it should be treated as legacy/unsupported. NuGet reference: https://www.nuget.org/packages/XMLDiffPatch/1.0.8.28

Resgen.exe - No dedicated CVEs for the tool itself (see Microsoft Security Update Guide: https://msrc.microsoft.com/update-guide); any security exposure would be tied to the underlying .NET Framework version.

If my explanation was helpful so far, kindly follow the instructions here so others with the same problem can benefit as well.

Answer 2

I cannot provide specific details about the lifecycle and support for the XMLDiffPatch component, including its EOS/EOL dates, current supported versions, or upgrade guidance, as this information is not contained within the provided context. For accurate and detailed information regarding Microsoft components, including lifecycle policies and support, I recommend checking the official Microsoft lifecycle documentation or reaching out to Microsoft support directly.
