----- Code Sample Notes -----

Four (4) assembly references are needed for a cache project:
CacheBaseLibrary.dll
CASBase.dll
ClientLibrary.dll
FabricCommon.dll
Import System.Data.Caching for code using Velocity
You must start with a CacheFactory. No parameters in the construct means to read from a configuration file.
From there, cache is accessed via a CacheName. You can use Cache.DefaultCache for the default (returns null) For CTP2, you cannot easily seek out if a region is created.
Cache.DefaultRegion is null as well.
There is quite a bit of log messages that are exposed by default in Velocity. Especially for a Cache Miss.

----- Installation Notes -----

CTP1 must be uninstalled first!
.Net Framework version 3.5
PowerShell version 1.0
Cluster configuration options
XML based
SQL Server (or SQL CE) based
Set cache cluster/host options
Cluster Name
Cluster Size: small (1-3), medium (4-6), large (7-10)
Cache Host port (default 22233)
Cache Cluster port (if configuring) (default 22234)
Max Server Memory

----- Configuration Notes -----

XML Configuration file or SQL Server
PowerShell is the de-facto configuration tool Desktop icon is created during installation for the PowerShell entrance Keep in mind that any parameter values are case-sensitive Basic help comes from
Get-CacheHelp
Other typical options (some have obvious names)
Start-CacheCluster
Stop-CacheCluster
Restart-CacheCluster
Get-Cache (shows the current Cache Names available and the regions)
New-Cache (creates a new cache name)
Remove-Cache (removes an existing cache name)
Get-CacheConfig (shows statistics for the cache node specified)
