Import-Module : Could not load file or assembly Microsoft.Bcl.AsyncInterfaces
I have this error only on PowerShell Core and not on Windows PowerShell 5.1 It was working fine until the latest release...
Import-Module: Could not load file or assembly 'Microsoft.Bcl.AsyncInterfaces, Version=8.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'.

I unlisted the module. It seems the last SSH.Net update added a dependency, so I can make it only work with one or the other at the moment. https://github.com/sshnet/SSH.NET/issues/1287
(I know nothing about powershell modules) Is it possible to package Microsoft.Bcl.AsyncInterfaces.dll alongside Renci.SshNet.dll?

Will you do a new release for the fix ?

I did and I get error’s depending on the version of .net used still trying to figure what broken with this latest nugget Sent from my iPhoneOn Jan 4, 2024, at 8:01 AM, Rob Hague @.***> wrote: (I know nothing about powershell modules) Is it possible to package Microsoft.Bcl.AsyncInterfaces.dll alongside Renci.SshNet.dll?

If I can fix it, seems the dependency messes stuff up when running under .ner standard 2.0

Where is Renci.SshNet.dll and SshNet.Security.Cryptography.dll? Should Microsoft.Bcl.AsyncInterfaces.dll be alongside those?

Perhaps there is some conflict somewhere. Does this show anything?

I set on the project <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies> to have it bundle all dependencies and still not working on PS7, it has to be some bug or something changed in PS. I did notice that when I look at [System.AppDomain]::CurrentDomain.GetAssemblies() | where {$_.location -like "user"} I see the module is loaded and SSH.Net assembly, but if I look at all assemblies some are blank for some reason
Now I'm completely lost. I can load it by hand, it is in the CAG but it can not find it .. .

I have a C:\Program Files\PowerShell\7\Microsoft.Bcl.AsyncInterfaces.dll which is version 5.0.0.0
The problem could be that the SSH.NET nuspec defines an exact dependency (with square brackets) on 8.0.0 and because PS7 has a dependency on a different version already, it refuses to load another.
You could try the following diff in SSH.NET:
diff --git a/src/Renci.SshNet/Renci.SshNet.csproj b/src/Renci.SshNet/Renci.SshNet.csproj
index 877b3b89..334df508 100644

<ItemGroup Condition=" '$(TargetFramework)' == 'net462' or '$(TargetFramework)' == 'netstandard2.0' ">

and try again with a local build of the library.
If things are still not getting anywhere, I would be in favour of removing the dependency from the library to unblock your module. It is not a necessary part of the library. cc @wojciechnagorski
@Rob-Hague Thanks!! it worked now on both versions of PS, I will do more tests before I update my module
Great
It would be useful if you could do a quick check with a local build using version 8.0.0 and see whether it still works (which would imply the problem would be fixed by https://github.com/sshnet/SSH.NET/pull/1288), or if it only works with a version <= 5.0.0 or whatever PS7 seems to be using (in which case, we should probably remove the dependency altogether)
@darkoperator @Rob-Hague I'm confused. If the csproj diff fixes it, wouldn't this mean the problem is version 8.0.0? In this case https://github.com/sshnet/SSH.NET/pull/1288 wouldn't fix it, since SSH.NET would still need 8.0.0 (it would just also accept 9.0 etc.).
If PowerShell can't handle the newer Microsoft.Bcl.AsyncInterfaces Version for whatever reason, it would probably be best for SSH.NET to require >=1.0.0 instead >=8.0.0 . I doubt that SSH.NET actually needs an up-to-date version since it's just a compat package for .NET Framework / .NET Standard.
yep, with version 1.1.0 it worked in terms of loading and establishing a SSH connection. Version 8.0.0 loading was the version causing the problem in PS 7
I think this one is covering it https://github.com/sshnet/SSH.NET/pull/1288
@mus65 I'm not so clear on the nuances of dll loading 🙂
Can you can modify your PR to take version >= 1.0.0?
@WojciechNagorski @Rob-Hague @darkoperator I updated my PR to fix both issues: https://github.com/sshnet/SSH.NET/pull/1288
@darkoperator PowerShell distributes Microsoft.Bcl.AsyncInterfaces, so if you want to load another version, that creates a conflict. Every time the PowerShell team changes the version of this assembly, it will break your module.
The technical explanation is here: https://learn.microsoft.com/en-us/powershell/scripting/dev-cross-plat/resolving-dependency-conflicts?view=powershell-7.4
In the quick version (this is contained in the previous document), if you define a class that implements IModuleAssemblyInitializer , when the module loads, you can insert code that allows you to load a library with the version of your choice (via an AssemblyLoadContext)
I'm giving you the repository of the person who worked on the subject at the time (same use case as the doc) https://github.com/rjmholt/ModuleDependencyIsolationExample/tree/master
A random example : https://github.com/PSBicep/BicepNet/blob/main/BicepNet.PS/LoadContext/ModuleInitializer.cs
Hello @darkoperator
Any update on the fix ? Should I use the latest release of the module ?
You can use the latest available in the gallery, at the moment waiting to see when they will push a new nugget with the fixed version. If in a couple of weeks they do not push one I will push my own version by compiling from the development branch.
