Can I remove old versions of .NET Core or .NET from my Hybrid IdP Server(s)

Version Affected:  20.06+

Description:  

When upgrading the IdP, depending on the version, different versions of .NetCore and .Net may be required to be installed as a prerequisite.

Cause:  

Older unsupported versions of software can have security risks and should be removed if at all possible.

Resolution:  

Based on the version of IdP installed, the below table shows what version of .NetCore/.Net is required.

The versions required must be adhered to and can not be upgraded to newer versions. The IdP has to be upgraded if you require a newer version of .NET Core.

During the upgrade, older versions are not removed and need to be manually removed. See the screenshot below showing a 23.07 upgrade. The items in the yellow boxes, the .NET Core 3.1.x items, can all be removed.

Once the .NET Core items are removed, you will need to do a repair on the .NET 6 Windows Server Hosting. This will properly update IIS since bits were removed previously. An IISRESET may be required but, if possible, Support suggests rebooting the server to make sure.
