Serialization Constructor
For your class to be serialized by Xml Serializer it is needed that it has a
default constructor... For your class, if you only have a constructor which
takes some fixed arguments and does not have a constructor which takes in no
arguments the serializer is not able to create an instance of your class to
serialize and so it fails with an error..
An unhandled exception of type 'System.InvalidOperationException' occurred
in system.xml.dll
Additional information: ApplicationName.ClassName cannot be serialized
because it does not have a default public constructor.
Similarly error might also occur in case you are using Activator class's
Create instance method for some type which does not have default public
constructor and you are not passing the constructor parameters...
So in short if it is not harming the base functionality it is always good to
have default constructor for your class...

PS: Most of the manufacturing industries have got their "Labor Unions" in
place... These bodies have helped putting a check on unscrupulous and
inhumane employers from ill-treating their employees... Manufacturing
industries have been here since ages, but IT industries have just came into
being... How about starting "ILU (Information technology Labor Union)" which
will be a social regulatory body... Contd in the blog...
