build wants to modify web.config

[Guest]

I have an asp.net solution with a web deployment project.

When we try to build/debug, we get the message:


An editor or project is attempting to check out a file that is modified in
memory, which will result in saving it. Saving files during the build process
is dangerous and can result in incorrect build outputs in future. Do you want
to continue with the check out?

If you check the web.config file out of VSS you don't get the message.
If you do a compare on the web.config, the only differences after the build
are that it reformatted some sections. For examples removing empty lines in
the connection strings section.

Why does this happen?

Hi Chuck,

From your description, you have an ASP.NET 2.0 web project which use "Web
Deployment Projecct" to build, however, when you build the WDP, it will
always report the following message, correct?

=================

process is dangerous and can result in incorrect build outputs in future.
Do you want to continue with the check out?
==================

As for this behavior, I think it should be specific to the VSS source
control environment. When you build the web deployment project, it may try
ensure all the files that has been at a stable version or is checked out
from source control. Is the file mentioned in the message the only that has
not been checked out? Also, as you said that the only difference from the
web.config file is the empty string has been removed, have you also checked
the version in VSS to see whether it is actually make the one in VSS
replace your current project's web.config file? To further verify this,
you can try creating a simple web project which contains some files that
are not checked out in VSS and try the web deployment project to see
whether building task will report such message. If so, we can determine the
behavior here.

Sincerely,
