Not able to refer Telerik.Sitefinity.Lists.Model and Telerik

I am trying to get list items from list programmatically. But I am not able to add reference to 'Telerik.Sitefinity.Lists' and 'Telerik.Sitefinity.Modules.Lists' dlls. I am getting error 'The type or namespace name 'Lists' does not exist in the namespace 'Telerik.Sitefinity' (are you missing an assembly reference?)'. Please give me a solution for this.

Hi Jinad,

You need to reference Telerik.Sitefinity.ContentModules.dll in your project

ListManager defined inside this DLL.  

'Telerik.Sitefinity.Lists' and 'Telerik.Sitefinity.Modules.Lists' namespaces placed inside this DLL as well
