Does the public token b4cc74ffd1b38c91 identify Skybow AG or the author(s) of DBMethods?
No. The original public/private key pair that is used to sign the DBMethods assemblies does not ship in the installation package with the source code. However, you cannot assume that a strongly named assembly with the public key token b4cc74ffd1b38c91 identifies the author(s) of DBMethods or Skybow AG in any way.
