ObjectCache in .net Windows Applications

Question

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?

Answer 1

Is the ObjectCache class included in .net framework 3.5

No.

You could still use the ASP.NET cache in a WinForms application if you reference the System.Web assembly:

HttpRuntime.Cache["key"] = "value";

and if you wanted to define more granular properties:

HttpRuntime.Cache.Add(
    "key",
    "value", 
    null,
    DateTime.MaxValue,
    TimeSpan.FromSeconds(3),
    CacheItemPriority.High,
    new CacheItemRemovedCallback(OnItemRemove)
);

Answer 2

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.
