Well, it's all moot now since I replaced WinSCP with SSH.NET, which is a much better SSH solution. I wasn't the one picked WinSCP for SFTP upload/download in ASP.NET anyway; that was my predecessor.

One thing I just noticed is that exe in the root folder is actually the previous version.

I have no idea where this is coming from.

It's a mystery. Anyway, when I go to import the package in IIS, I just uncheck that extra WinSCP.EXE so it doesn't end up in the web site root folder. The one in ~/bin is all I need.

– I have installed VS 2022
– Started new "ASP.NET Core Web App" project, keeping all defaults (including .NET 6.0)
– Added WinSCP 5.19.5 NuGet package
– Added some dummy code to Program.cs that uses WinSCP.Session to make sure the WinSCP .NET assembly is linked in (probably not needed)
– Went to Publish > Web Server (IIS) > Web Deploy Package, clicked Publish

I got ZIP file with only one WinSCP.exe file in: Content\C_C\Users\martin\source\repos\WebApplication1\WebApplication1\obj\Release\net6.0\PubTmp\Out\

Where do we differ?

Don't know what I am doing wrong:
Content/C_C/Users/<username>/Source/Repos/<git repository name>/<project name>/obj/Release - Production/Package/PackageTmp/WinSCP.EXE
and
Content/C_C/Users/<username>/Source/Repos/<git repository name>/<project name>/obj/Release - Production/Package/PackageTmp/bin/WinSCP.EXE
The first path contains all the ASPX pages, web.config, etc. The second path contains the compiled DLLs.

The WinSCP.targets file looks OK:

I've tried that. And I still have only one copy of WinSCP.exe in the zip file. In:
Content\B_C\<project>\<project>\obj\Release\net5.0\PubTmp\Out\WinSCP.exe

Right click on project in project explorer and select 'Publish...'. The Publish Method I have chosen is 'Web Deploy Package' and the location of where that package should be created. After publishing, the location contains, among other things, the zip file that you can copy to your IIS server and install using Deploy->Import Application... in IIS Manager.

For some reason WinSCP.EXE is included in the root folder of the deploy package as well as the /bin folder. I'm not sure why. I can uncheck it when Importing, or even delete it from the zip file I suppose, but it shouldn't be there to start with.

I did mention this is an ASP .NET web site application, so a bin folder should be present.

How exactly do you create the "publish zip file"? I do not see that option in VS.

When I select publish to a "Folder", I get only one copy of winscp.exe – in the root. And there's no bin folder. Though I have VS 2019. Did something change?

I have installed the latest stable WinSCP NuGet package as part of an ASP .NET web server in Visual Studio 2022. When I publish my web site to a deploy package, WinSCP.EXE is copied to both the root folder and the /bin directory in the publish zip file. How do I keep it out of the root folder and just leave it in /bin?
