C# Signature:

[DllImport("kernel32.dll")]
[return: System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.I1)]
static extern bool CreateSymbolicLink(string lpSymlinkFileName, string lpTargetFileName, SYMBOLIC_LINK_FLAG dwFlags);

VB.NET Signature:

<DllImport("kernel32.dll")> _
Private Shared Function CreateSymbolicLink(ByVal lpSymlinkFileName As String, ByVal lpTargetFileName As String, ByVal dwFlags As SYMBOLIC_LINK_FLAG) As Boolean
End Function

User-Defined Types:

SYMBOLIC_LINK_FLAG

A DWORD or in .NET a UInt32.

0x0 The link target is a file.

0x1 The link target is a directory.

Notes:

The unmanaged prototype contains a return directive because the CreateSymbolicLink API function returns BOOLEAN, a one-byte data type. The default marshaling for bool is four bytes (to allow seamless integration with BOOL return values). If you were to use the default marshaling for BOOLEAN values, it's likely that you will get erroneous results. The return directive forces PInvoke to marshal just one byte of the return value.
