Takes me a half hour today to figure out how to get the assembly attribute AssemblyKeyName to work. The normal provided MSDN docs are always describing the way how to use the AssemblyKeyFile attribute and simply hint: "... or install the key into the CryptoServiceProvider (CSP)". I didn't like the idea to provide the company keypair file to each dev.Machine. So here it is:

once> sn.exe -k companyKeyPair.snk
each dev.client> sn.exe -i companyKeyPair.snk CompanyKey

AssemblyInfo.cs: AssemblyKeyName("CompanyKey")]
