Hi,
I have a brand new VS2010 installed on a Win2008R2 machine.
I started getting this error when debugging a WCF service project:
"Attempted to read or write protected
memory. This is often an indication
that other memory is corrupt."
When I started developing a web site a week later, this became consistent - I can't debug it.
The stack dump reads:
at
Microsoft.VisualStudio.WebHost.Host.ProcessRequest(Connection
conn) at
Microsoft.VisualStudio.WebHost.Server.OnSocketAccept(Object
acceptedSocket) at
System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(Object
state) at
System.Threading.ExecutionContext.Run(ExecutionContext
executionContext, ContextCallback
callback, Object state, Boolean
ignoreSyncCtx) at
System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem()
at
System.Threading.ThreadPoolWorkQueue.Dispatch()
at
System.Threading._ThreadPoolWaitCallback.PerformWaitCallback()
I tried searching online, and some recommend turning off the "Suppress JIT Optimizations" in the Debugging options - this dos not seem to make a difference.
Clearly the problem is with the built in web server. But am I doing something wrong? Is there something I can do? Or is this a known bug?
Thanks for your time,
Guy
Update 12/31: Today I tried using CassiniDev as a replacement to the original VS2010 WebServer - exact same result. My suspicion is that there's some internal conflict between VS2010, Windows Server 2008R2 and maybe the fact that it's a 64 bit OS. I switched to using IIS as my debug server - and that seems to work, with some annoying side effects.
My conclusion: do not use a 64 bit server system as your dev machine. Develop on 32bit - deploy to 64bit.
Side conclusion: there are some scenarios Microsoft's QA doesn't test.
