-// General Information about an assembly is controlled through the following

-// Version information for an assembly consists of the following four values:
-//
-// Major Version
-// Minor Version
-// Build Number
-// Revision
-//
-// You can specify all the values or you can default the Revision and Build Numbers
-// by using the '*' as shown below:

-// In order to sign your assembly you must specify a key to use. Refer to the
-// Microsoft .NET Framework documentation for more information on assembly signing.
-//
-// Use the attributes below to control which key is used for signing.
-//
-// Notes:
-// (*) If no key is specified, the assembly is not signed.
-// (*) KeyName refers to a key that has been installed in the Crypto Service
-// Provider (CSP) on your machine. KeyFile refers to a file which contains
-// a key.
-// (*) If the KeyFile and the KeyName values are both specified, the
-// following processing occurs:
-// (1) If the KeyName can be found in the CSP, that key is used.
-// (2) If the KeyName does not exist and the KeyFile does exist, the key
-// in the KeyFile is installed into the CSP and used.
-// (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
-// When specifying the KeyFile, the location of the KeyFile should be
-// relative to the project output directory which is
-// %Project Directory%\obj\<configuration>. For example, if your KeyFile is
-// located in the project directory, you would specify the AssemblyKeyFile
-// attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
-// (*) Delay Signing is an advanced option - see the Microsoft .NET Framework
-// documentation for more information on this.
