Hi,
One of the common errors that may occur when publishing your application to live server is that you may get the following error.
Unable to find script library '/aspnet_client/system-web/1-1-4322/webvalidation.js'try placing this file manually or reinstall by running 'aspnet-regiis-c'
This would occur particularly if you are using validation controls in your application.
The aspnet_client folder contains the WebUIValidation.js which is required to handle the asp.net validation controls.
If the aspnet_client folder is missing in the IIS virtual directory listing you may encounter the above error. to resolve this, you may need to run the following from command prompt
%windir%\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis -c
This will install the aspnet_client folder to the default virtual directory website.
Further, if you are using a sub-virtual directory you need to have this aspnet_client folder in your root directory as well.
To do this, you can manually copy the folder to your root directory.
This would help in solving the error.
