VS Debug Problem with IE8

 

Since this is my first post on Weblogs, I decide to write about a problem that has been opened frequently on ASP.NET official forum which is VS debugger crashes with IE8.

 

  I had answered the same problem 4 times, so I hope that some one will found this post very helpful if he is facing the same problem.

 

 

How VS debugger could be crashed with IE8?

 

If you opened multiple instances of IE8 and you attempt to debug your project, you mostly will have the issue where VS debugger just stops and ignores your break points!

 

 

Why was that?

 

Well, IE 8 has a feature called Loosely-Coupled Internet Explorer (LCIE) which results in IE running across multiple processes.
http://www.microsoft.com/windows/internet-explorer/beta/readiness/developers-existing.aspx#lcie

Older versions of the Visual Studio Debugger get confused by this and cannot figure out how to attach to the correct process. 

 

To overcome this issue, you need to disable the process growth feature of LCIE by follow the below steps:

1)  Open RegEdit
2)  Browse to HKEY_LOCALMACHINE -> SOFTWARE -> Microsoft -> Internet Explorer -> Main
3)  Add a dword under this key called TabProcGrowth
4)  Set TabProcGrowth to 0

 If you run into the same problem on Vista or newer, you will also need to turn off protected mode.

And then go a head and start debugging your code :)

Re: Mohammad,

Hello Mohammad,

Your webapplication should  be compiled with zero errors.

Also delete the old files in the ASP.NET temporary file.

.

The behavior described above got corrected automatically, on my XP Pro setup at work... don't know how, except I noticed that when entering or exiting Debug I had to be careful to slow down my clicking and wait... if I go to fast trying to Debug something back to back rapidly... it fails.  It worked for a long time a year or more, and all of the sudden it comes back and I could not resolve it.

BUT CONSIDEER THIS SCENARIO!

I believe the issue I now face is related in the sense that it is due to IE 8, on my brand new setup at home(see below).

The VS Debugger times out after about 1 minute+ debugging even the simplest 'Hello world' .NET VB app

This is a brand new setup... all I did is install and work thru all the issues to get everything to work properly.

- I am able to create projects

- I access the Database from the SQL Server Explorer and make changes to schema and data

- I access the Database thru the site(able to login etc...)

- DEBUG???!!! FORGGGGGET IT! 2 minutes max and YOU ARE OUT!

The Visual Studio Debugger whether in Studio Debug or IIS Debug times out within a 2 minutes mark.

The debugger times out on the simplest VANILLA 1 page 'Hello world' app.

Take note: This is a clean NEW install.

My Current SETUP:  (new setup at home)

- Dual Core 64bit/32bit(x86)

- WINDOWS 7 Pro(latest updates installed)

- Visual Studio 2008 Pro SP1

- Framework 3.5(you know...piggybacked on 2.0, 3.0, SPx...)

- SQL Server Express 2005 (part of the Visual Studio install), SP3 installed on top

- IIS 7.5 comes with WINDOWS 7 Pro (all integrated, does not show in Programs installed or Updates installed, one turns it on by going to windows features)

 Incidentally:  The manager for 7.5 still is listed in program files as the 6 version. (will verify that and see what the discrepancy is)

- Latest version of IE (8...)

# November 15, 2009 2:09 AM

NIc Martel said:

- forgot to mention that I applied the fix above, to no avail.

- Also I ommitted to mention that I have tried all of the suggested configs and setups I found on the internet to no avail.

- and the path stated above to temp ASP.NET files, I was unable to correlate to the WINDOWS 7 mappings.

Hopefully that is that it will take.

# November 15, 2009 2:14 AM

Nic Martel said:

New Discovery:

When I run the app using IIS instead of the VS built-in Web Server, I fails to see my data... I don't know why yet.

Have not investigated.

All I did was to go in Project-MySite Properties-Web TAB and changed it to VS Dev Server... and immediately attempted a login succesfully.

Thus I may have 2 problems.

Hi,

I am not to able to debug my application in Win 7 with IE 8.I tried your fix but I see that there is alredy a key existing in the registry with the same name.
