I have some code for a .Net 2.0 winforms application which modifies the app's config file. The code works without error
for me, but when another developer runs the same code in Visual Studio debug he receives a permissions exception on the
statement
config.Save(ConfigurationSaveMode.Modified);

At the file/folder level he has full permissions and I would think we have the same default code access security. So
my question would be why the permissions error and what to do to resolve. I would also like to know if there any issue
in this to expect when deploying to production (to an end users pc)

Brad,

I'm curious about this issue as well. I experienced it under .NET 1.1 on my
machine. None of the other developers (probably a total of about 30 or so
that had done development work on the app) ever experienced the problem, nor
have any of our users since. I was the "lucky" one.

In an attempt to fix the problem, I had a freak caspol accident (I think it
was caspol) and managed to deny the administrator access to the
\Windows\System32 directory. After reinstalling Windows, the problem went
away and haven't seen it since. I'm curious what the cause was, though.

Pete

Hi Brad,

Can you explain to me what "in Visual Studio debug" mean in your post? Do
you mean that the problem occurs only while the developer is using VS
debugger to debugging the code? Also, can you provide the permission
exception type and detailed call stack of this exception to me? This will
help us to give analysis.

Finally, is this problem reproducable on other machines? If so, is it
possible for you to create a little sample project to help me reproduce it
locally? Actually, this is the most efficient way to help me understand it
and debug it. Thanks.

Best regards,
Jeffrey Tan
