OK, so I implemented your first code snippet. It works.

What I left out before was that this all goes in a repository. I currently have a MongoDB repo, and now I'm implementing the IRepository interface to deal with the serialized version of the data. Now I have a new issue:

This Works
public T Get(Guid id)
{
    return Data.Where(x => x.Id == id).FirstOrDefault();
}
This Doesn't Compile
public T Get(Expression<Func<T, bool>> predicate)
{
    return Data.Where(predicate).FirstOrDefault();
}
The error is "'List<t>' does not contain a definition for 'Where' and the best extension method overload 'Queryable.Where<t>(IQueryable<t>, Expression<func<t, bool="">>)' requires a receiver of type 'IQueryable<t>'"

The problem is that List<t> isn't an IQueryable. If I change method signaature to accept a delegate instead of an expression, it works.
public T Get(Func<T, bool> predicate)
{
    return Data.Where(predicate).FirstOrDefault();
}
I could add this method to the interface, but I'd rather not change existing code if I don't have to. And it causes abiguity beetween the two Get methods.

I'd like to hear your thoughts on this. And thanks for your help so far.
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
