Question

When Strong typing an Assembly in .net, I can create the keypair (private) like this:

sn -k keypair.snk

And extracting the public key from it like that:

sn -p keypair.snk public.snk

But once I am in the property of a project, under Signing tab to select the Sign key,

which key do I choose? The keypair or public key?

In which circumstances within my organization would I need the public key?

Many Thanks,

You need the original file which contains both the public and private keys (the one generated with the -k option).

In which circumstances within my organization would I need the public key?

Quote from the documentation:

This public key can be used to delay sign an assembly using the
/delaysign+ and /keyfile options of the Assembly Linker (Al.exe). When
an assembly is delay signed, only the public key is set at compile
time and space is reserved in the file for the signature to be added
later when the private key is known.

Here’s another article on MSDN explaining this process.
