Disadvantages of Lazy?

Question

I recently started using Lazy throughout my application, and I was wondering if there are any obvious negative aspects that I need to take into account when using Lazy<

Answer 1

I've come to use Lazy mainly because of it's concurrency capabilities while loading resources from database. Thus I got rid of lock objects and arguable locking patterns. In my case ConcurrentDictionary + Lazy as a value made my day, thanks to @Reed Copsey and his blog post

This looks like the following. Instead of calling:

MyValue value = dictionary.GetOrAdd(
                             key, 
                             () => new MyValue(key));

We would instead use a ConcurrentDictionary>, and write:

MyValue value = dictionary.GetOrAdd(
                             key, 
                             () => new Lazy(
                                 () => new MyValue(key)))
                          .Value;

No downsides of Lazy noticed so far.
