System.InvalidOperationException Unable to generate a temporary class error

[Eric]

Hello,

I'm trying to debug a VB.NET dll that calls a web service. I've
customized my References.vb to do some functionality I don't believe
would be possible otherwise.

When I hit the MyBase.New() line in the references.vb file I'm getting
the following message (the name of the cs file changes each time):

System.InvalidOperationException: {"Unable to generate a temporary
class (result=1).
error CS2001: Source file 'C:\WINDOWS\TEMP\ghvplywm.0.cs' could not be
found
error CS2008: No inputs specified

I've tried giving my ASP.NET Machine Account Write access to the
C:\WINDOWS\TEMP directory then full control of this directory, but I'm
still getting the error message. Any idea what to look at next?

I'm running IIS using my user ID, and I'm an admin on my box, so this
didn't make a whole lot of sense.

From the SysInternals website, I downloaded logonsessions.exe, a

command line utility.

I then ran logonsessions.exe /p > logonsessions.txt and did a search
for process ID 1636, which was the ID of the dllhost.exe process that I
was attached to in the VS 2005 IDE.

It showed that it was running as:

[7] Logon session 00000000:00094e16:
User name: MyMachineName\IWAM_MyMachineName
Auth package: NTLM
Logon type: Batch
Session: 0
Sid: S-1-5-21-1196832610-2522517657-3672563552-1018
Logon time: 12/13/2006 3:24:16 PM
Logon server: MyMachineName
DNS Domain:
UPN:
1636: C:\WINDOWS\system32\dllhost.exe

So I gave MyMachineName\IWAM_MyMachineName read and write permissions
to the C:\WINDOWS\TEMP directory and my error went away.
