Q:

How do you show your asp.net app version? 

Setting the scene:
My asp.net web application carries a version number which is incremented during every release.  We're releasing every week internally for our test team and after four weeks or so to our client. 
The question:
I want to include the version number on our application.  What methods have you used so that your web app carries the version number?  meta tag?  simply added it to the footer? 

A:

If you are in contact with the client a lot (for bug fixes or changes) you should keep the version number in a place that is easy to find (such as the footer).   You will find yourself asking the client what version they are running, if they cannot find it it is frustrating for both the client and the support staff. 
Make sure your footer is a user control or that the version is stored in either a database table or a resource file so that you update once rather then going through each page updating.   My recommendation is a user control and if you want to track versioning store the version numbers in a database and read it into your user control. 
You can take the MS route of doing a help->about given a menu and displaying the version number in say a js popup or on another page. 
If for some reason you do not like the version number on a footer or even a help menu popup and you do not deal with the client regularly you can put it as meta data or in the source code of your HTML.
