How to use WinSCP simply with C# csc compiler?

Beginner in C# question, please be patient :)
I see some nice manuals on how to get WinSCP working with NuGet or in Visual Studio. I currently have no possibility for those. I just use a source code file (dosomejob.cs) and compiler to produce my exe file (dosomejob.exe).
How do I get WinSCP working with just the csc compiler?
Can I point to the WinSCP exe or dll from my source code file?

Based on csc.exe reference external .dll file, this works:
Assuming you have contents of the ".NET Assembly" package (the WinSCPnet.dll and WinSCP.exe) in the same folder.

Thank you, works like a charm :)
