Delegate
A delegate is an object that holds a reference to a method with a particular parameter list and return type.
It is basically like an object-oriented, type-safe function pointer.
Delegates basically make it possible to treat methods as entities. You can then assign a delegate to a variable or pass it as a
parameter.

length vs size in jquery
.size() is a Method call, which returns the length property.
So you either call the method to return the property, or you retrieve the property directly.

return; //this is equivalent of 'continue' for jQuery loop
What the difference between text(), html(), val() functions in jQuery ?
$("#div1").html('<a href="example.html">Link</a><b>hello</b>'); //will render an actual link
$("#div2").text('<a href="example.html">Link</a><b>hello</b>'); //html is visible to the user Note: tags are encoded
val() method only work with control like input, select, button etc. It not work with div, span, p etc.
Function vs method
A function is a piece of code that is called by name. It can be passed data to operate on (ie. the parameters) and can optionally return data (the
return value).
All data that is passed to a function is explicitly passed.
A method is a piece of code that is called by name that is associated with an object. In most respects it is identical to a function except for two
key differences.
It is implicitly passed for the object for which it was called.
It is able to operate on data that is contained within the class (remembering that an object is an instance of a class - the class is
the definition, the object is an instance of that data).

What's the difference between List<string> and IEnumerable<String>?
A List<string> is a concrete implementation of IEnumerable<string>. The difference is that IEnumerable<string> is merely a sequence of string but
a List<string> is indexable by an int index, can be added to and removed from and have items inserted at a particular index.
Basically, the interface IEnumerable<string> lets you stream the string in the sequence but List<string> lets you do this as well as modify and
access the items in the lists in specific ways. An IEnumerable<string> is general sequence of string that can be iterated but doesn't allow random
access. A List<string> is a specific random-access variable-size collection.

Cancelling WCF calls with large data?
It is a good practice to use a stream if the file size is above a certain amount. At my work on the enterprise application we
are writing, if it is bigger than 16kb then we stream it. If it is less than that, we buffer. Our file service is specially designed to handle this logic.
When you have the transfer mode of your service set to buffer, it will buffer on the client as well as on the service when you
are transmitting your data. This means if you are sending a 300mb file, it will buffer all 300mb during the call on both ends before the call is
complete. This will definitely create bottlenecks. For performance reasons, this should only be when you have small files that buffer quickly.
Otherwise, a stream is the best way to go.
If the majority or all of your files are larger files I'd switch to using a stream.
