Why is it faster to check if dictionary contains the key, rather than catch the exception in case it
...the stack has to be unwound etc.
On the other hand, accessing a value in a dictionary by its key is cheap, because it's a fast, O(1) operation.

if(!dict.TryGetValue(name, out item))
return null;
return item;
This accesses the di...

... implemenation is configured for the given bean name, the class now relies directly on Spring to provide that dependency and can't get it any other way. You can't just make your own mock implementation in a test class and pass that to it yourself. This basically defeats Spring's purpose as a depende...
