I'm try on Ultimate version and Express version.
Reinstall many time from web install and offline install.
What shouldI do ?

Hi againyangxiao,
Someone alredy fix out this problem.
Root of it is "Current language for non-Unicode programs".

VS2010B2 will work only English , other language programwill crash.
It really surprised me.

Hi, your screenshot refers to a Console application. Does the problem happen with WPF apps or with other kinds of applications too? With regard to WPF, at which point does the problem occur? I mean, when you create the project, when you activate the designer, when you run the application...

I can suggest you to run the VS 2010 Ultimate edition and attach the Visual Studio Debugger to get complete information. My suggestion is:

1. run an instance of Visual Studio 2010 Ultimate
2. run a second instance of Visual Studio
3. in the first instance running, go to Tools|Attach to process. This will show up a window where you can select the process for attaching the debugger to. Select the second instance of Devenv.exe
4. in the second instance, try to reproduce the problem
5. when you're done, detach the debugger from within the second instance.

Finally I suggest you to file the result log to http://connect.microsoft.com

Hi, VS2010B2 is error whenI activate the designer or activate code file(like .vb).
I'm follow your suggest and find this but where are logfile location?(I'm really don't know where it are).

System.StackOverflowException was unhandled
An unhandled exception of type 'System.StackOverflowException' occurred in Microsoft.VisualStudio.Shell.UI.dll

From this instance, go to Debug-> Save dump with miniheap, and create a dump file. Please attach dump file when you get it.

Thanks,
Yang

Hi Rich,

Can you let me know your configuration, including OS (Version, language). I assume "other language programwill crash" refers to non-English OS.

Thanks,

Hi Rich,

Thanks for reporting this issue. We're able to catch a callstack and we have fixed this issue for VS2010.
