  Hi,
  
  Summary: 
  
  I am getting FileIOPermission and Dialog permission exceptions when trying to Debug/Run a VC#2008 Express project. The problem occurs when running in a VM guest with the project stored in a shared directory on the VM host. Running and debugging succeeds if the project is moved out of the host share and into the VM guest.
  
  Details:
  
  I am setting up a test environment.  I have a virtual machine guest running WinXP and Visual C# express 2008. The VM guest is running on a WinXP host.
  
  The host has a shared directory that the guest can read and write to with all permissions. In Explorer I can move and copy files between the VM Guest and the share on the host.
  
  I have a VC#2008 project in the host's shared directory. I can rebuld the project on the guest while its sitting in the hosts share, but when I try to run or debug it fails with FileIOPermissions and Dialog permissions (at points where the app tries to open files and show the file dialog).
  
  I tried assigning permissions from the .NET configuration tool in the guest but saw no change in behavior, even when giving all code full trust. I did not try assigning perissions this way on the host.
  
  I get the same behavior whether the guest is running in Virtual PC or VMWare Server.
  
  I have also obeserved the same behavior in 3rd party non-.NET apps, where they can run in the guest and save their docs in the guest, but cannot save their docs in a share on the host. In this case they either crash or appear to succeed but dont actually save the file on the host share.
   
  
  Any insights are appreciated. Thanks.
  
  Mike
