Binding redirect issue -> Could not load file or assembly

[MichalGranat]

Hello,

I have WPF application targetting .net48 with following references:

A -> APP

A -> B -> APP

Both A & B references some other 3rd party lib (Microsoft.Extensions.Logging.Abstractions installed as nuget, let's nickname it L) .
Case is that B was referencing newer L than A. In result final APP build contains newer version of L.

When APP is launched as application everything works fine.

Issue is, that same *.dlls are used in TestStand in API. Unfortunatelly TS is throws following exception:

As B references L in version 8.0.2, there is this one in final build, I suppose. When A is tryining to use it, there is this exception.

Now, it's clear what's the issue, but I cannot find any reasonable solution. 
 -> Editing SeqEdit.exe.config is not acceptable for me
 -> Editing app.config seems to be without effect

Could someone provide any help, please?
Thanks and regards,
Michal

The issue arises from version conflicts in referenced libraries. Ensure both A and B reference the same L version. Consider separate build configurations, assembly binding redirection, or isolated AppDomains.

I've tried to setup assembly binding redirection, but without success. Where should I do this?

Question is why APP has no problem with this? Why TestStand is not able to handle it in the same way?

In net framework You can crate wrapper that registers to this event as fisrt step that sequence calls:

AppDomain.CurrentDomain.AssemblyResolve += CurrentDomainOnAssemblyResolve;

It will display what is missing, You can point to the right dll

I'd really like to know how can I set binding redirection in TestStand. All redirections set in VS project (App.config) seems not to work. 

I've found something about editing SeqEdit.exe.config, but this seems as a bad idea to me.
