IE 8 + VS 2010 don't seem to play well with each other. I have an ASP .NET project running in .NET 4.0 mode. THe project contains two solutions, one is a solution that generates a DLL for my business logic layer, and the other is the ASP .NET website.

What happens is that I can debug the application usually the first time. Then if I close the IE window to quit debugging I can go change some code. I either do change code, or do not change code, it doesn't matter, occasionally (and it is very random), when I start debugging again, all I get is a blank IE window. You can see the title of the page and it looks like it might continue to come up, but it does not.

Pages that seem to have the most issues are pages with many controls on it. We use DevExpress controls almost exclusively in our projects and one of the .ASPX pages that I set as the start page has a lot of DevExpress controls on it. When launching that page it occasionally comes up, and sometimes it does not.

The database server the application gets data from is only used by one person (ME), and there is no blocking occuring on it, so it's not pausing due to a blocking issue as I've checked for deadlocks on the SQL Server.

I'm running Windows 7 x64, VS 2010, all latest patches. Also occurred on Windows 7 x32, VS 2010 with all the latest patches as well (windows update is not indicating I have anything left to patch).

Additionally, when this blank IE window comes up and you view source, you can see that part of the page HTML has been generated by ASP .NET but it stops at random spots during page generation.

My Visual Studio 2010 has been hanging frequently. It is doing it right now. Every two seconds, it freezes and says Not Responding. If I manage to switch the start-up project from a WPF project to a console project in the solution, it works fine again.

Is there a patch I need to download for this?

Which hotfix is supposed to solve this? (I have regularly looked in https://connect.microsoft.com/VisualStudio/Downloads and still do not see anything really matching).

We work in a large solution with several web projects, and VS2010 gets stuck *at least* 10 times a day on each developer machine. The solution frequently hangs simply when trying to display the markup of an aspx page (or sometimes even a html page!). No high CPU usage, no disk reads, but claims to be "busy" indefinitely (smells like a deadlock or the UI thread waiting on a thread that went away). I now tend to edit markup with Notepad++ outside of Visual Studio to spare me the grief.

Since you declared this fixed on September 28 of last year, VS 2010 on my machine alone will have had similar hangs well over 1,000 times. If that is due to the same bug, it is definitely NOT fixed for me! Today is July 15, 2011, well over 9 months later.

FYI, notice this is marked as FIXED. You will have to contact Microsoft and see if they will create a hot fix for this issue. Apparently it is a threading logic bug.

This is similar to the following:
