CallContext

Here's something I cobbled together to mimic the Java ThreadLocal class. I wanted a nice way to wrap up the CallContext class, I call it "CallLocal". It provides typesafe access through generics, which saves a bit of typing (no pun intended). It looks something like this:

using System;
using System.Runtime.Remoting.Messaging;
namespace Framework.Core.Utility
{
    public class CallLocal<T>
    {
        private string _keyName;
        public CallLocal(string keyName)
        {
            if (string.IsNullOrEmpty(keyName))
                throw new ArgumentNullException("keyName", "keyName cannot be null or empty.");
            _keyName = keyName;
        }
        public T Get()
        {
            return (T)CallContext.GetData(_keyName);
        }
        public void Set(T data)
        {
            CallContext.SetData(_keyName, data);
        }
    }
}

Knock yourself out.
