Hi,
These are the steps to be followed to sign an already built assembly
Open Visual Studio Command prompt.
Generate a KeyFile:
sn -k keyPair.snk
Obtain the MSIL for the provided assembly:
ildasm myAssembly.dll /out:myAssembly.il
Rename/move the original assembly
Create a new assembly from the MSIL output and your assembly
ilasm myAssembly.il /dll /key= keyPair.snk
Bye..
