Salve sto realizzando un servzio di cache per un mio applicativo e sto utilizzando il caching delle microsoft enetrprise library
con questo codice

private ICacheManager CacheManager;

...
this.CacheManager = CacheFactory.GetCacheManager();

Oggetto _Oggetto = new Oggetto(1, "Uno");

this.CacheManager.Add(_Oggetto.Name, _Oggetto);
...

nell'app.config

<configSections>
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

Alla chiamata this.CacheManager = CacheFactory.GetCacheManager();
Ricevo il seguente errore:
Microsoft.Practices.ObjectBuilder2.BuildFailedException: The current build operation (build key Build Key[Microsoft.Practices.EnterpriseLibrary.Caching.ICacheManager, Cache Manager]) failed: The given path's format is not supported. (Strategy type Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ObjectBuilder.ConfiguredObjectStrategy, index 2) ---> System.NotSupportedException: The given path's format is not supported.
