Why do we need to restart IIS after copied DLLs into Assembly

Whenever we copy Dlls into assembly folder we need t开发者_运维知识库o restart IIS. It takes more time and we need to do it for every changes. So it is full of wasting time.

Is there any alternative option instead of restarting IIS.

I am working in Sharepoint 2007, windows server 2008

We restart the IIS to reset Application pool as lot of things in SharePoint are cached. The alternative option is you can recycle the application pool of the application for which you have deployed the WSP or DLLs

Its the ASP.NET behavior: Asp.net Reinstalling a DLL into the GAC

reset Application pool as lot of things are cached & all sessions connected to your Web server (including Internet, FTP, SMTP, and NNTP) are dropped
