We have upgraded our oData Asp.Net appllication to .Net version 4.7.2 and we have reinstalled all the dependencies ie odata nuget packages and we have started getting the following error

Any help would be appreciated to fix the issue

It seems to be that reinstalling odata nuget packages adds System.Linq, System.Linq.Expression, System.Reflection, System.Runtime.Extensions to references and also adds assembly redirection. Deleting the references and removing the assembly redirection solves the issue.

@rbmanian75 Since the issue was resolved, can I close it?

Hi,

To resolve the issue we need a manual interaction after installing the odata packages. It would be better when installing the packages these referenaces System.Linq, System.Linq.Expression, System.Reflection, System.Runtime.Extensions should not be added to the project like it is doing for .Net 4.6

@rbmanian75 Sorry to hear the experience but it looks like a VS nuget package management related issue.

I'm having the same problem. It's a good thing I found this thread or I would be totally stuck. Does the fault truly lie with nuget package management?

I am getting the same error message when I have created a Blueprism object to execute a PowerShell command and capture the response. The process is running fine when I am trying to execute commands like Get-ADGroup, Get-Acl but it fail with the above error when I am executing the command as Get-QADGroup etc.
