One of the principles I insist on is to always try my build on a clean environment and simulate installation as if it was done by QA. Lately I've noticed that I keep falling on errors hidden deep in the aspx files. So, why not using the old and familiar aspnet_compiler.exe tool? It is located at C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727 and it is quite easy to use.
As a VS add-ins freak I've started thinking on an amazing add-in that will integrate to the VS and will listen to build events and display the results at the output pane. Heck, why not add some coffee serving capabilities?
It took me about 10 minutes of googling to stumble on this blog. Mike Hadlow had a genius in its simplicity idea. Use the POST BUILD EVENT!
All I need to do is put the following line in the post build event: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_compiler.exe -v / -p "$(ProjectDir)\"
Now, All that is left is to make the process of adding this line to each and every web project in our team to be automatic.
I have just the add-in for that :)
