New Update for Microsoft AppFabric!

Microsoft releases cumulative update (CU) packages for Windows Server AppFabric 1.1 from time to time.

Each cumulative update package contains all of the fixes that were released in previous update packages. At the time of this posting there are four cumulative update packages that have been released:

Cumulative update package 1 for Microsoft AppFabric 1.1 for Windows Server
Cumulative update package 2 for Microsoft AppFabric 1.1 for Windows Server
Cumulative update package 3 for Microsoft AppFabric 1.1 for Windows Server
Cumulative update package 4 for Microsoft AppFabric 1.1 for Windows Server

These are the AppFabric 1.1 cache dll versions Microsoft has released:

RTM: 1.0.4632 (29-Nov-2011)
CU1: 1.0.4639 (20-Feb-2012)
CU2: 1.0.4644 (29-May-12)
CU3: 1.0.4652.2 (27-Nov-2012)
CU4: 1.0.4653.2 (28-Mar-2013)

<

p>CU3 and later versions including CU4 require .NET 4.5 on cache servers as documented on the KBs. However .NET 4.5 is not a prerequisite on cache clients to use client binaries in CU3 or a later version.

Windows Server AppFabric Cache Administration Tool

This update adds improved PowerShell cmdlets for AppFabric cache management.

This update introduces new set of AppFabric Server PowerShell cmdlets to make it consistent with other Microsoft server products and keeps the older cmdlets enabled as aliases to make sure that existing scripts continue to function.

After you apply this update, when you open the AppFabric Server PowerShell prompt, PowerShell may prompt you for permissions to run a script if your existing Execution Policy prevents it. To use the AppFabric PowerShell cmdlets, you have to enable running of signed scripts.

Cache Clients and Local Cache (Windows Server AppFabric Caching)

This update fixes an issue where items in a local cache may not expire because of a defined policy.

Because of a race condition, some objects in a local cache may not expire as expected. Therefore, a client may potentially receive data that is not up to date.

GetCache() API for Windows Server AppFabric Cache

This update fixes an issue where the GetCache() method may fail with the “An item with the same key has already been added” System.ArgumentException.

You receive the following exception message when you call the GetCache() method:

System.ArgumentException: An item with the same key has already been added.

Known issue with Cumulative Update for Microsoft AppFabric 1.1 for Windows Server

Important This update applies to the caching functionality of AppFabric 1.1 only. We recommend that you install the update only on servers that are running the AppFabric cache or that are using the AppFabric cache client.

Issue

After you install the update, the AppFabric Configuration Wizard incorrectly reports the status of the Persistence and Monitoring configuration as “Not configured.” Additionally, the user interface status is incorrect.

To verify that the services are running, follow these steps:

  1. Open the Powershell administration console.
  2. Run the Get-ASAppMonitoring –Root command to verify the configuration of the state.
  3. Run the Get-ASAppInstanceStore –Root command to verify the instance store connection strings.

This issue can safely be ignored as it does not affect the functionality of either AppFabric Hosting Services or the services that are hosted by AppFabric Hosting Services.
