The SharpLink repository contains currently a single C# class that can be used to
create file system symbolic links from a low privileged user account. The class uses
a technique that was first identified by James Forshaw
and implemented within the symboliclink-testing-tools.
The usd.Symlink type defined in this repository allows you to create symlinks directly
from PowerShell in an object oriented fashion.
In future, more link related classes and functionalities may be added. This is why we have
chosen to store the usd.Symlink class in an repository instead of a Gist.
The usd.Symlink type is intended to be used from PowerShell:
PS C:\> $type = @"
<CODE>
"@
PS C:\> Add-Type $type
PS C:\> $s = New-Object usd.Symlink("C:\ProgramData\target.txt", "C:\Users\Public\example\link")
PS C:\> $s.Open()
[+] Creating Junction: C:\Users\Public\example -> \RPC CONTROL
[+] Creating Symlink: Global\GLOBALROOT\RPC CONTROL\link -> \??\C:\ProgramData\target.txt
[+] Symlink was setup successfully.
PS C:\> echo test > C:\Users\Public\example\link
PS C:\> type C:\ProgramData\target.txt
test
PS C:\> $s.Close()
[+] Removing Junction: C:\Users\Public\example -> \RPC CONTROL
[+] Deleting Symlink: Global\GLOBALROOT\RPC CONTROL\link -> \??\C:\ProgramData\target.txt
[+] Symlink deleted.SharpLink ports some of the symlink functionalities from the symboliclink-testing-tools to C#. The general idea as well as the required Win32 API calls were taken from the symboliclink-testing-tools repository. Furthermore, the C# code for creating and deleting the junctions was basically copied from the below mentioned reference.
