Is the ObjectCache class included in .Net Framework 3.5?
If not, is there an alternative for storing objects in cache, ( in windows applications not asp.net)?
And does anyone have any online resources or code snippets that demonstrate how to use the ObjectCache class?
ObjectCache is introduced in .NET framework 4. If you are using a prior framework, you can use Microsoft Entreprise Library caching.
I do not recommend you using HttpRuntime.Cache as it is not intended to be used outside of asp.net applications.
