VS2008 Hang Debugger

Question

I am using Visual Studio 2008 Team System Service Pack 1 (SP1), and I noticed an annoying tendency for the IDE to hang within a few (10-15) seconds when I stop debugging the application. At first, I thought this only happened with WPF applications, but I watched the behavior in Windows Forms applications and on ASP.NET sites. I made a number of changes to Options based on this previous post and performed exhaustive Google / MSDN searches, but still haven't found a way to stop this.

Does anyone have any idea?

@ korona - No, that can't be fixed. Thank you for your offer.

More research at ProcMon shows this interesting tidbit, not sure if this is related:

8:45:46.6790857 AM WindowsFormsApplication1.vshost.exe 7684 FASTIO_CHECK_IF_POSSIBLE C:\WINXP\Microsoft.NET\Framework\v2.0.50727\CONFIG\enterprisesec.config.cch FAST IO DISALLOWED Operation: Read, Offset: 48, Length: 12 8:45:46.6793569 AM WindowsFormsApplication1.vshost.exe 7684 ReadFile C:\WINXP\Microsoft.NET\Framework\v2.0.50727\CONFIG\enterprisesec.config.cch FAST IO DISALLOWED Offset: 508, Length: 12 

This is repeated several times, like hundreds of times, then switches to another path:

 8:45:46.7470314 AM WindowsFormsApplication1.vshost.exe 7684 FASTIO_CHECK_IF_POSSIBLE D:\documents and settings\myusername\Application Data\Microsoft\CLR Security Config\v2.0.50727.42\security.config.cch FAST IO DISALLOWED Operation: Read, Offset: 48, Length: 12 8:45:46.7472187 AM WindowsFormsApplication1.vshost.exe 7684 ReadFile D:\documents and settings\myusername\Application Data\Microsoft\CLR Security Config\v2.0.50727.42\security.config.cch FAST IO DISALLOWED Offset: 508, Length: 12 

And it repeats again many times, with slight changes in the offset of each iteration. Maybe not related, but ....

Answer 1

Looking at your ProcMon results, it seems like it's a CreateFile () call that takes all the time. I assume all activity is awaiting the return of this thread. You can verify this - with some difficulties - in Process Explorer (also part of the previously bundled SysInternals package) using the Threads tab in the Properties window.

So, if CreateFile is the cause of the lock, this suggests that this is a delay in Windows itself. What Pierre said - pay attention to network shares - was also my first instinct. In the past, I had many seemingly inexplicable slowdowns when Explorer had a comparison with a share that I could not get at the moment, although at that time I did not work on these shares.

Can you test this feature by untying all your drives and unplugging it from the network? Is there D: a separate physical disk from C :? If so, see if this is faster if you move the assembly directory to C :.

Answer 2

I observed this behavior on one of my development machines and Visual Studio 2005. The problem was caused by the fact that Visual Studio was trying to reach some non-existent network resource (I do not remember exactly why). You can give Process Monitor a try to make sure that your Visual Studio tries to do something stupid when it finishes debugging and returns to normal view, Maybe because you have a broken plugin in the toolbar or toolbar.

Answer 3

Bingo! This has something to do with network share. I don’t know which one yet, but now it’s pretty easy for me to understand what I know where to look. I took your advice, unhooked my network adapter, disconnected the network drives, and started again. Do not hang! Thank you so much. This will greatly improve life.

Answer 4

From the site below, I found several possible solutions.

http://social.msdn.microsoft.com/Forums/en/vsdebug/thread/e9c5da47-a194-4051-a3d5-28b404263b3f

It’s best to work with Internet Explorer. Then go to the menu "Tools" - "Internet Options" → "Advanced" → "Security", uncheck the box "Check publication of publisher certificate"

Answer 5

Is it a hangover even with basic apps? How to create a new window shape and then debug it, or is it just with more complex applications? Because I noticed this before (maybe not quite 10-15 seconds, but there was a bit of a lag that I noticed), but when I just tried to debug a relatively simple application for windows, I did not get it at all.

Answer 6

Good question. I created a very simple Windows Forms application:

 private void button1_Click(object sender, EventArgs e) { MessageBox.Show("I am saying hello."); } 

Still 10 seconds when closing the form.

Answer 7

@ Pierre - I launched ProcMon on devenv.exe and timed the application to close. The results are interesting. It hung for 15 seconds, and you can see it hanging in ProcMon. From 8:45 to 8:45:46 no activity was registered. I'm going to get confused with the filter in ProcMon and see if there is something outside of devenv.exe, but here is what I wrote from devenv.exe around the 15 second interval:

Thank you for your help.

I'm not 100% sure that this is the same problem, but my VC ++ behaves in a similar way during debugging. This happened in most cases when you broke into a broken program, so again I’m not sure that this is the same problem, but it may be worth a try.

Reason: A debugged process dies when there are locks obtained by mutexes that the Text Services Framework uses to render text. When other applications try to render any text, they end up being locked until the debugged process completes.

Correction: Disable advanced text services by opening the control panel, regional and language settings, languages, details ... advanced, and selecting the "Disable advanced text services" checkbox.

Sorry if this is not related to your problem, but it certainly helped me with a debugger acting and blocking my system.

Great, as in my case, then. Could you find out which network resource Visual Studio is trying to get. You can try wireshark for further study. You will see what traffic your computer generates ...
