Error: “value cannot be null parameter name publickey”

I just had a very strange error message in my visual studio 2010 SharePoint project…

When building the project everything goes well, but when packaging it or deploying it I got this error message:

“value cannot be null parameter name publickey”

Also, trying to open the package editor in visual studio to take a look at the “preview of packaged manifest” showed me the same error:

Google did not prove to be useful as I did not find anything close to this error message.

Well, in the interest of saving you time, let me just say that after some search around the project I found that the strong name signing of my project was missing the signature file (SNK), which produced an unsigned DLL, and as such – I guess caused this issue with the package building.

Hope this will at least save some time to anyone else out there,

Happy SharePointing!

    Thanks for the post. Saved me some major time as I forgot to sign the assembly.

    Thank you.
    In my case I'd remove file key.snkm then I went to properties of project and create a new key without password. :)

    I had an snk file, but I had to select my project and: right click -> Properties -> Signing -> Choose a strong name key file -> enter my snk file name
