With post we like to share how easy it is to find App fabric or Distributed cache version.
So lets get started :)
The easiest way is to manually check what version of App Fabric you are using or CU applied to App Fabric
Go to Control Panel > Program and Features. Check for App Fabric and you can see the version.
Second way is thru PowerShell.
Run below cmd to get the details about App Fabric a.k.a Distributed cache.
(Get-ItemProperty "C:\Program Files\AppFabric 1.1 for Windows Server\PowershellModules\DistributedCacheConfiguration\Microsoft.ApplicationServer.Caching.Configuration.dll" -Name VersionInfo).VersionInfo.ProductVersion
Happy SharePointing :)
