I use the following for Authenticode signing in my batch files:

C#

SET SignToolMs="C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Bin\signtool.exe" sign /f %cd%"\MyProject\MyCertificate.pfx" /p myname
%SignToolMs% %cd%"\MyProject\bin\x86\Release\MyProgram.exe"

I first used Dotfuscator for signing, but found this was not reliable.

Change import to using, import is VB.NET syntax !
