I am always astounded how often I inherit code from smart developers who know what they are doing, but still do not take the time to close and destroy objects. As much fuss is made about memory management and such, this is still an area of coding where laziness abounds.

.Net memory management and garbage collection is intended to free up our need to manage memory at a micro level, but at the same time it is criticized for not freeing up memory fast enough and then blamed for application issues and server slowness. For best practices, never rely on inherent memory management. Where you can, close and DISPOSE!

The Overview

   “We do not pretend to have achieved perfection — but we do have a system — and it works.”  – Klaatu

When developing ASP.NET web applications a very common approach to maintaining state is to store variables into the Session.

Session is just one way to store data. Here are some other ones that I know of. Can you think of any others?

• Application (global) – uses server memory.
• Session (user) – can use user memory and/or database storage.
• Data cache (global, but can be user specific with proper handling) – uses server memory.
• Viewstate (web page) – rides along with the page.  No server memory.
• Database (global and user) – includes SQL, XML, local files, etc.
• Cookie (user) – stored on the client’s computer and accessed via the browser.
• Query String (user) – doesn’t use server memory – just a lot of developer patience.
• Form fields (web page) – popular in HTML and classic ASP development.

Recently our organization (The Net Impact) made the decision to rebuild our entire development environment. As most know this can be both a daunting and yet exciting venture. During the planning phase we had numerous discussions concerning which source control utility to implement and we finally decided to test Subversion versus Microsoft Team Server.

One of the complaints I have had in the past with Subversion is how clunky interfacing with it has been. I feel that in this day and age any command line interface is past its prime, and having to run external third party interfaces is simply annoying. I wanted something fully integrated into our development tools mimicking the functionality of eclipse and PVCS I had used years back.
