Jeffery Palermo says 'Classic WebForms More Mature Than ASP.NET MVC': "Is Classic WebForms More Mature Than ASP.NET MVC?".
It seems to be subjective, but what I want to know is, what exactly "mature" software is?
The answer is very subjective. But basically if the software can answer to most of these criteria (in no order of importance):
Then it can be considered "mature".
It is important to note that different clients would expect different levels of "maturity". A large corporation would demand that the software it uses is secure enough to protect its sensitive data, and that the software is supported by a support rep available 24/7. As opposed to a small private project of your own which you might care much less about security, and you do not need (nor can afford) a service package which includes 24/7 customer support.
So ,maturity differentiates according to the client, but the basic criteria remain the same.
