From the 'Create New Release' dialog, go to the Recognition tab then click the 'Advanced' button at the bottom. On the 'Advanced Recognition Parameters' dialog, click the 'Registry' tab.
I see "Microsoft .NET Framework 4.8 SDK 4.8.03928" listed under my Heuristic discovered software.
I took a look at the CA provided signature as .NET 4.8 was not being detected on my system and have asked the content team to review the registry key they use to detect.
If you look at one of the VA provided .NET signatures you can use that as a template for creating you own.
We have published a new signature. Please run the CIC download from the Engine job. Wait a while, then trigger the AM Agent to collect software inventory.
Sorry been on leave.
I had a look today, seems to be much better.
Thank you for your assistance.
