Visual Studio - VS hangs when debugging

VS hangs when debugging

Paul Nichols

I wondered if anyone has encountered the behaviour I’m getting when I debug most areas of my ASP/VB.Net application. Our solution contains about 7 projects and is of a reasonable size, the projects are both a mix of asp applications and dll’s.

When I’m debugging and a breakpoint I’ve set is hit I often find I loose control of VS and it hangs for half a minute. When I get control again the variable or line I was about to evaluate can no long be evaluated and when I hover over variables the t
ool tip shows me the declaration rather than the current value!

This is making my development hell so if anyone can help then I would be very grateful

Regards
Paul

Hi Paul,

1. Do you experience the same behavior if you create a new very simple application such as a "Hello World" one?
2. Can you replicate this on more than the current machine of yours?
3. Have you tried to uninstall the IIS?
4. You may also want to re-register the IIS with regiis_aspnet -i

Here is the scenario where this typically happens.

When you step through code, the debugger evaluates all of the properties
that are displayed in the locals window. This means that it is actually
calling into your code and displaying the results.

When you get a hang like this it typically means that one of the properties
the debugger is accessing is hitting an infinite loop or is just taking an
incredibly long time to respond. Once the debugger gives up about half a
minute later it stops displaying properties to prevent hanging again.

One solution is to go to Tools -> Options -> Debugging -> General and
uncheck "Allow property evalution in variable windows". This will disable
the evaluation of properties. You can still right click on them and have
them evaluated

Thank you guys

You were nearly right Jared, it was my watch window, I don't use it loads, but I'm embarrassed to admit that I didn't realise that it remembered your watches even when you've shut down VS.
I had about 20 objects being evaluated each time I hit any break points, plus I hadn't set that option in the debugging properties, so the debugger was timing out.

Life's great again now thanks :)
