 +====== WinSCP .NET Assembly and COM Library ======
 +The WinSCP .NET assembly ''winscpnet.dll'' is a .NET wrapper around WinSCP's [[scripting|scripting interface]] that allows your code to connect to a remote machine and manipulate remote files over SFTP, FTP, WebDAV, S3 and SCP sessions from .NET languages, such as [[#csharp|C#]], [[#vbnet|VB.NET]], and others, or from automation environments supporting .NET, such as [[library_powershell|PowerShell]], [[library_ssis|SQL Server Integration Services (SSIS)]] and Microsoft Azure WebSites and Functions.
 +The assembly is also exposed to COM, and as such it can be used from variety of other programming languages and development environments--e.g., [[library_com_wsh|WSH-hosted active scripting languages]] like JScript and VBScript, [[library_vb|Visual Basic for Applications (VBA)]], [[library_perl|Perl]], and Python.
 +
 +The assembly targets .NET Framework 4.0 and .NET Standard 2.0.
 +
 +===== [[purpose]] Purpose of the Assembly =====
 +
 +The library is primarily intended for advanced automation tasks on Microsoft Windows that require conditional processing, loops or other control structures for which the basic [[scripting|scripting interface]] is too limited.
 +
 +You can also use the assembly to write scripts that [[guide_custom_commands_automation|extend functionality of WinSCP GUI]].
 +
 +The library is not a general purpose file transfer library. It particularly has a limited support for an interactive processing, and as such it is not well suited for use in GUI applications.
 +
 +Because the assembly uses ''winscp.exe'' internally, it is also difficult (but not impossible) to use the assembly within a restricted environment like a ==web== server (e.g. with ASP.NET), that limits or even restricts execution of external processes.
 +
 +===== Downloading and Installing the Assembly =====
 +First you need to [[library_install|download and install the assembly]].
 +
 +===== [[using]] Using Classes from WinSCP .NET Assembly =====
 +  - Create an instance of the ''[[library_sessionoptions|WinSCP.SessionOptions]]'' class and fill in all necessary information to allow an automatic connection and authentication of your session.
 +  - Create an instance of the ''[[library_session|WinSCP.Session]]'' class. Optionally you can hook handlers of some events of the class.
 +  - Open the session using ''[[library_session_open|Session.Open]]'' method, passing instance of your ''WinSCP.SessionOptions''.
 +
 +Once the session is opened, you can use any of the ''WinSCP.Session'' [[library_session#methods|methods]] to manipulate remote files, e.g.,
 +  * ''[[library_session_getfiles|Session.GetFiles]]'' to [[task_download|download files]],
 +  * ''[[library_session_putfiles|Session.PutFiles]]'' to [[task_upload|upload files]] or
 +  * ''[[library_session_synchronizedirectories|Session.SynchronizeDirectories]]'' to [[task_synchronize_full|synchronize directories]].

 +===== [[net]] Converting Script to Code Based on .NET Assembly =====
 +When you find yourself limited by [[scripting]] capabilities, you may consider [[library_from_script|converting your script to code that uses WinSCP .NET assembly]].
 +
 +===== [[license]] License =====
 +The WinSCP .NET Assembly is a free library: you can use it, redistribute it and/or modify it under the terms of the [[https://www.mozilla.org/MPL/2.0/|Mozilla Public License Version 2.0]].
 +
 +Because WinSCP uses [[license|the GPL license]] it's important to keep the %%GPL%% license file around.((Simply said, keep all files from ''WinSCP-X.X.X-Automation.zip'' package together.)) Your software doesn't have to be licensed under GPL as the  WinSCP .NET Assembly is using WinSCP as an executable, via its public [[scripting|scripting interface]], and not as a library.
