Does edtFTPnetPRO have a dependency on System.WindowsForms?

Question

My company is migrating to Azure, and I'm using edtFTPnetPRO version 10.1.0 in an Azure Function app. When downloading files I receive the following exception:

Could not load file or assembly 'System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The system cannot find the file specified.   at EnterpriseDT.Net.Ftp.FTPConnection.InvokeDelegate(Boolean preferGuiThread, Boolean permitAsync, Delegate del, Object[] args)

   at EDICommand.FTP.EDIFTP.Pull(String pathToFiles, String destPath, Boolean bDelSourceFiles) in D:\Git\AzurePrototypes\EDICommand\EDICommand\FTP\EDIFTP.cs:line 474

Is there a dependency here? I use .Net 6 for the Azure Function app, but I've not been able to find any edtFTPnetPRO version 10.1 package at nuget.org. I simply include the dll and create a project reference to it. It seems to fail during event callbacks.

Hi,

Version 11.0.0. included the below addition:

• Modify obfuscation so that assembly dependencies can be extracted.

See here

We don't have a public nuget package as ours is a commercial package that requires a subscription to obtain the latest version. 

In other correspondence, this user has stated that "I’ve downloaded edtFTPnetPROCORE.dll version 12, and that seems to be working fine with .Net 6.".
