@darylbowman I haven't verified this, but my guess is because Microsoft.Net.Http is the newer version that should likely be used for .NET Core.

Should I be expecting to find that in the bin?

I don’t know, I haven’t looked myself yet. That’s a question I guess for Acumatica or maybe in the release notes?

Actually, I may be wrong about this, sorry. I’m not sure Microsoft.Net.Http is a newer version. The article I was looking at was older than I thought.

I never realized it was a problem because Rider (or MSBuild) fixed it for me behind the scenes.
I’m not sure why they removed it; maybe they want us to use the framework-specific version?
The reference diagnostics popup a bit misleading here because there is no System.Net.Http.dll in the Bin folder.
