23//
24// Major Version
25// Minor Version
26// Build Number
27// Revision
28//
29// You can specify all the values or you can default the Revision and Build Numbers

37//
38// Use the attributes below to control which key is used for signing.
39//
40// Notes:
41// (*) If no key is specified, the assembly is not signed.
42// (*) KeyName refers to a key that has been installed in the Crypto Service
43// Provider (CSP) on your machine. KeyFile refers to a file which contains
44// a key.
45// (*) If the KeyFile and the KeyName values are both specified, the
46// following processing occurs:
47// (1) If the KeyName can be found in the CSP, that key is used.
48// (2) If the KeyName does not exist and the KeyFile does exist, the key
49// in the KeyFile is installed into the CSP and used.
50// (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
51// When specifying the KeyFile, the location of the KeyFile should be
52// relative to the project output directory which is
53// %Project Directory%\obj\<configuration>. For example, if your KeyFile is
54// located in the project directory, you would specify the AssemblyKeyFile
55// attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
