@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.

@darylbowman @Kyle Vanderstoep @Tony Lanzer 

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.

Hi ​@darylbowman were you able to find a solution? Thank you!

Not really, no.

​I'm encountering an issue similar to the one discussed in the thread "Why is System.Net.Http.dll not included in 24 R1?" on the Acumatica Community forum. In Acumatica 2024 R1, the System.Net.Http.dll is missing from the Bin folder, leading to reference errors in my customization project.​Acumatica Community+2Acumatica Community+2Acumatica Community+2

As noted in the forum, this absence might be due to a shift towards using framework-specific versions of the library. However, this change has caused build issues in my project.​Acumatica Community

Has anyone found a workaround or solution to this problem? Is there an official recommendation from Acumatica regarding the use of System.Net.Http in 2024 R1 customizations?

​@Priyam1614 I believe I was able to add it as a file to the customization so it would publish along with it.

This is obviously possible. My main question is this as well:

Hi,

I attempted to upload the System.Net.Http.dll file under the Files section in the customization, but I'm still encountering the same error (please see the attached screenshot). I'm unsure if I made any mistakes—do you have any suggestions or guidance on this?

Thank you!

Hi ​@Priyam1614,

Have you got any resolution on above issue?

How can we add System.Net.HTTP reference from assemblies while upgrading to 24 R2?

Hi,

Unfortunately, I haven't found a resolution to the issue yet. I'm still trying to figure it out.  
If anyone has any suggestions or insights, they would be greatly appreciated!

Hi ​@Priyam1614,

I'm not sure if this was the right approach, but I created a new DLL, moved my code to Visual Studio, and added the System.Net.Http reference using the Manage NuGet Packages option. This resolved the issue, and I’m now able to publish the package successfully.
