Debugging Silverlight in IE8 (on Windows 7)

I’ve recently moved to Windows 7 RC and I couldn’t be happier. Its a great OS…but there is one annoying side effect.  The new IE8 auto recovery mode kills the session if the website becomes unresponsive.  Cool if you’re on a dead site, but remarkable bad if you’re trying to debug code.

I was looking for a workaround when Pascal Pare from Microsoft came to the rescue.  There is a registry setting that can enable/disable the feature. By default it is enabled.  The key is:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Recovery]

Setting the AutoRecover to “2” enables it (the default value) and setting it to “0” disables it.  Hope this helps!
