This document provides information about Microsoft AppFabric, including supported operating systems, hardware requirements, installation instructions, configuration, and administration. AppFabric allows for in-memory caching, database caching, and page output caching. It can be installed on Windows Server 2008 R2 and later or Windows 7 and later.

3.  In-memory caching
 DB caching
 Page output caching
 2010
◦ Windows Server AppFabric 1.0
 Microsoft AppFabric 1.1 for windows server

4.  AppFabric can be installed on the following
operating systems:
 Windows Server 2012
 Windows Server 2008 R2
 Windows Server 2008 Service Pack 2
 AppFabric can be installed for development
and testing on the following operating
systems:
 Windows 8
 Windows 7
 Windows Vista Service Pack 2

5. Supported Architectures:
 32-bit (x86)
 64-bit (x64)
◦ Hardware requirements:
 Minimum Hard Disk Space: 2GB
 Computer with an Intel Pentium-compatible CPU that
is
 1 GHz or faster for single processors;
 900 MHz or faster for dual processors;
 or 700 MHz or faster for quad processors.

6.  All features of AppFabric require a .NET
Framework:
 Microsoft .NET Framework 4 and optionally requires
Microsoft .NET Framework 3.5 Service Pack 1
 Internet Information Services (IIS) 7
 Internet Information Services (IIS) 7 Hotfix #980423
 IIS Web Deployment tool
 Windows PowerShell 2.0 (final version) (this is
not required for users on Windows 7,Windows
Server 2008 R2, or later)

9.  Cache Host
 Cache Cluster
 Cache Client
 Cache server
 Cache Configuration storage
 Cache Administration

11.  Named Caches
 Regions
 Cached Objects

12.  To target the correct version of the .NET
Framework
◦ Open your Visual Studio .NET project.
◦ In Solution Explorer, right-click the project name and
then select Properties.
◦ Select the Application tab of the Project
Properties dialog.
◦ Verify that the target framework version is .NET
Framework 2.0 or higher.
◦ In Visual Studio 2008, uncheck the Client-only
Framework subset checkbox. In Visual Studio 2010,
select .NET Framework versions that do not specify
"Client Profile".

13.  Install AppFabric Client on dev machine.
 To add references to the AppFabric caching
assemblies
◦ Open your Visual Studio .NET project.
◦ In Solution Explorer, right-click the project name and
then select Add Reference.
◦ Select the Browse tab of the Add Reference dialog.
◦ Navigate to the .WindowsSystem32AppFabric
directory.
◦ On 64-bit systems, the AppFabric directory will not be
directly visible. To work around this problem, create a
new folder with the name “SysNative” and copy
AppFabric folder to this folder. This results in navigating
to the C:WindowsSysNativeAppFabric directory in this
step.

14.  Add a reference to the following two
assemblies:
◦ Microsoft.ApplicationServer.Caching.Client.dll
◦ Microsoft.ApplicationServer.Caching.Core.dll.

15.  %temp% folder
 AppServerSetup(yyyy-MM-dd H-mm-ss).log
 http://msdn.microsoft.com/en-us/
library/aa368542(VS.85).aspx
 Microsoft.ApplicationServer.Configuration
(yyyy-MM-dd H-mm-ss) <process code>.log
 http://msdn.microsoft.com/en-us/
library/ms681381(v=VS.85).aspx.

16.  Session state caching
 Other data caching

17.  Does not restart auto after reboot.
 Work around.
◦ Set the AppFabric Caching Service's Startup type to
be Automatic
◦ Another option is to schedule a startup task to
execute the Use-CacheCluster and Start-CacheHost
commands.

18.  For development and testing environments,
◦ with licenses for Windows Vista (SP2 or later) and
Windows 7 at no additional cost.
 For production environments,
◦ with licenses for Windows Server 2008 (SP2 or later) and
Windows Server 2008 R2 at no additional cost.
 In production environments,
◦ only active directory domain joined machines.
◦ The high availability caching feature in Windows Server
AppFabric is available only on Windows Server 2008/R2
Enterprise Edition.
 There are no client access licenses for Windows
Server AppFabric.

25.  Install Critical Windows Updates
 Install the .NET Framework
 Install AppFabric
 Configure AppFabric
 All machines should be in same domain.
 Create a domain user for caching service.
 Share UNC location.
