What is the preferred naming convention for Func method parameters?

Question

I admit that this question is subjective but I am interested in the view of the community. I have a cache class that takes a cache loader function of type Func

Answer 1

I typically actually use the work delegate in my naming, to make it obvious that this parameter is receiving a delegate. For example, I'd potentially name the above:

public static class Cache
{
    public TResult Get(string cacheKey, Func cacheLoadingDelegate) 
    {
        // Implementation
    }
}

I do this specifically to avoid confusion from the suggested naming in the question. cacheLoader sounds too much like an object, and loadResult like an object/type (the result itself). I also don't personally like using function or method, as a delegate is not actually a function, but rather a delegate - a type that references a function.
