MSI Issues

[escher4096]

My project requires some post build steps to make it 'ready' for
deployment. It needs to tweak the app.config and it needs to build out
a nasty blob of XML (this takes a long time). The XML is specific to
the build version of the application. My post build works exactly as I
would expect it to does all of the stuff I want it to do.

It modifies: [my project]/bin/debug/[app name].exe.config
It builds: [my project]/bin/debug/temp/nasty_blob_of.x ml

I run my application and everything is happy. However I can not get
these files into my MSI. The setup project goes for the 'primary
output' of my project which it determines as

[my project]/bin/debug/[app name].exe
[my project]/[app name].exe.config

I can not see a way to modify what the setup project has deemed to be
my primary outputs. I can not add secondary outputs. I can add static
files but these are not static files (the setup project wants to put
the included the files under source control which of course would
cause issues since the post build needs to modify them).

I realize I could modify my app.config (the one the setup wants to
include) in a pre-build setup, but since I would need to add a post
build to change it back it would be messy and an annoyance (there has
t be a better way). There don't appear to be any post/pre-build steps
to the MSI and there doesn't seem to be away to include generated
files that are not the direct result of a compile step.

Any help would be greatly appreciated.

Thanks
