.NET 6 is now EOL

[NikMartin]

Hi, I was just notified by my security team that .net 6 is EOL by Microsoft as of 11/12/2024 : Microsoft .NET | endoflife.date 

Are there any plans to update the runtime dependencies? I see that even Enterprise 11.x still uses .net 6.

"Enterprise 11.x" covers 5 versions, so making general statements about software requirements should be avoided since requirements can, and have, changed over 2 1/2 years.

No version of ArcGIS 11.x requires any version of .NET unless one is using Server Object Extensions (SOEs) and Server Object Interceptors (SOIs) and has installed the .NET Extension Support feature.  If that feature is not installed, talking .NET versions is moot.

For the .NET Extension Support feature, ArcGIS 11.0, 11.1, and 11.2 depend on .NET 6 while ArcGIS 11.3 and 11.4 depend on .NET 8.  Given ArcGIS 11.2 is a short-term support release, and ArcGIS 11.1 enters Extended Support in May 2025, I would not expect Esri to make any big changes to those releases at this point.

We have released a technical article discussing this and support for .NET 8 with Enterprise 11.1; Is ArcGIS Enterprise Web Adaptor (IIS) 11.1 supported on .NET 6 and .NET 8? https://support.esri.com/en-us/knowledge-base/arcgis-enterprise-web-adaptor-iis-11-1-now-supported-o...

Hope this helps.
