Increasing Debug Time in Sharepoint 2010

If you’re developing for SharePoint 2010 the Application Pool has a setting called Ping Maximum Response Time with a default value of 90 seconds. In effect, this means that debugging your Web Part, Page, etc. in SharePoint 2010 will only work for 90 seconds and then you get this:

"The web server process that was being debugged has been terminated by Internet Information Services(IIS). This can be avoided by configuring Application Pool ping settings in IIS. See help for further details."

The error is really self explanatory and very helpful. To resolve this:


- Click on Start->run->inetmgr

- Locate your application pool and select Advanced Settings on the menu on the right

- Modify the value of Ping Maximum Response Time (Seconds)


You can also increase the value for future Application Pools via Set Application Pool Defaults by selecting the root node of Application Pools in IIS.
