@Hesoka009 this dependency on System.Net.Http.WinHttpHandler.dll is unexpected.
From the server causing this error: Can you browse to C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Net.Http.WinHttpHandler, extract System.Net.Http.WinHttpHandler.dll and upload it to this discussion?
What version of .NET is installed on this machine?

[Yvand]

@Hesoka009 EntraCP requires at least .NET Framework 4.8.

[Hesoka009]

its wereid because it was working 2weeks ago in this servers.

Should i update so my .net version ?
How can i check the version of the wsp installed for Entracp?
and what is the number indicated in the log trace 27095462, is that the version of the wsp ?

I am asking to check if my update-spwolution worked correctly

[Yvand]

The DLL is located in C:\Windows\Microsoft.NET\assembly\GAC_64\Yvand.EntraCP\v4.0_1.0.0.0__65dc6b5903b51636\Yvand.EntraCP.dll
EntraCP cannot run for without at least .NET Framework 4.8, as it is compiled with this version as requirement, as you can see here.

[Hesoka009]

i checked internally and the issue if we install .net 4.8 it can impact our custom application.

Can i usse and old version of Entracp that is compatible with .net 4.7 without updating it?

Thanks for your feedback

[Yvand]

No, EntraCP was compiled with .NET 4.8 from the beginning.
And I strongly discourage you to install AzureCP. It is deprecated for years and uses completely outdated dependencies
