WebApplication MSI Install Issue

As part of the compatibility testing of the new web Application developed by us, the client asked us to give the msi install so that they could test it on one of their test server. When they installed in the Test Server the msi failed. I asked them to run it in the Log mode and send me the Logfile.
msiexec /i /l*vx C:\SomeDirectory\SomeFilename.log

When I went through the logfile I found the following issue:
RROR : [03/03/2010 08:42:56:992] [RegisterAspNet ]: The error
indicates that this version of ASP.NET must first be registered on the machine.
ERROR : [03/03/2010 08:42:56:992] [RegisterAspNet ]: FAILED:
-2147024893

This error message is so generic that I really don’t know what is the real cause. After cheking each configuration between my dev machine and the Test Machine, we finally realized that the Web Service Extension dint have ASP.NETv2.0.50727. I asked them to re-register the Web Service Extension by running aspnet_regiis –I and it solved the problem.

Validation Controls no use

From all the experience I’d in ASP.NET, I’ve realized that there is no real value of Validation Controls. Most of the UI Validation still needs custom Javascript validation.
Even if the validations of Validation Controls fit our requirements we may still not able to use it b’coz of its poor way of displaying validations.

Web Application Publish doesn't build all projects

When a Web Application is published it doesn't automatically do a build of all the projects if the solution. So before Publish do a build and rebuild at the solution level.
