If you are also facing same error as above…then i have its solution. Here it is
Solution:
Just open your web.config file and locate <cachingConfiguration> under it <backingStores>
under it you will have <add encryptionProviderName
this tag has attribute type here you will find
type=”Microsoft.Practices.EnterpriseLibrary.Caching.BackingStoreImplementations.NullBackingStore, Microsoft.Practices.EnterpriseLibrary.Caching, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null” name=”Null Storage”/>
have you seen this publicKeyToken is null..so how can it work..yes this is the solution.
so just add publicKeyToken value to assembly’s Token…so you will have now
<add encryptionProviderName=”" type=”Microsoft.Practices.EnterpriseLibrary.Caching.BackingStoreImplementations.NullBackingStore, Microsoft.Practices.EnterpriseLibrary.Caching, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a” name=”Null Storage”/>
Error is resolved..
