I know we tend to stay away from Tech Support Hell (tm Dell) here and
focus more on process/tools, however I wanted to ask a question to
those possibly more experienced with AppDomains than I am. I pretty
much have a solution to the problem, however I just want to make sure
I'm not missing anything.
The problem is this, I have an Updater scenario where I need to have
the Updater update itself. This is the perfect scenario for
AppDomain.ShadowCopyFiles, however I cannot find a way to have a .NET
executable start with the ShadowCopyFiles turned on by default. Does
anyone here know of a way?
My current solution is to have a launcher.exe that will likely never
change spin up a new AppDomain with ShadowCopyFiles turned on, then
execute my updater.exe within that AppDomain. This allows the updater
to be updatable while minimizing any unchangable code. I still feels
like a kludge to me though. What do you guys and gals think?

There isn't another way unless you are into CLR hosting, and I assure you that this is not the way to go. You can even have the updater.exe update the...

BAD Mojo that, Bad Mojo. Don't do this, ever. You are going to run into so many risks of ruining things. As a simple example, consider this: /bin/ myApp.exe ...
