I create a fully signed assembly with a certain key.
AssemblyInfo.cs looks like this:

[assembly: AssemblyDelaySign(false)]
[assembly: AssemblyKeyFile(@"..\..\key.file.here.snk")]
[assembly: AssemblyKeyName("")]

Then I do "sn -R assembly.dll otherkey.snk".
sn reports that assembly was resigned successfully.

However, if I output public key token before and after re-signing
(sn -T) it is the same.

If I extract binary public key from re-signed assembly (sn -e)
and from key.file.here.snk (sn -p), they are binary identical.

If I extract public key from otherkey.snk, it is different.

It looks like resigning did not occur - assembly is still signed
with the old key.

What am I doing wrong?
