Great sample!!
(all comments are based on using ServerManifestCheck for
ChangeDetectionMode)
After playing with the code for a little while and watching what it does,
I noticed that the downloader code does not leverage existing DLLs in the
original install directory. It downloads everything and then merges the
code from the original install directory (please correct me if I am wrong).
Wouldn't it make sense to copy the original installation folder to the
download folder first and then start downloading? (The downloader code is
smart enough not to download files that are the same) Since the downloader
code does not take into account the contents of the existing installation
folder it ends up downloading everything from the update server. What if
you only need to deploy a fix to a 10KB DLL?
Some other observations:
* By linking the update version with the assembly version in the main
application EXE, you cannot send down an update without recompiling the
main EXE. What if you just want to deploy a minor DLL change? Then you
need to recompile the EXE as well.
* Another side effect of linking the main EXE is that you cannot rollback
if something goes wrong (yes, I know you need to be careful but sometimes
you may need the option of downgrading a user to a Known Good Version).
* appdomain setting does not work when restarting the EXE - it immediately
closes (someone else posted this issue as well).
I modified the code to store the version number in the in the
appstart.config and use this version to determine "when to download" rather
then depending on the main app EXE assembly version - this allows a
rollback or incremental update (main EXE does not need to be recompiled).
Mark, is there a better place to send feedback?

I just wanted to let you know there's a new auto-deployment article
written by Jamie Cool on the Windows Forms team on GotDotNet
http://www.gotdotnet.com/team/windowsforms/appupdater.aspx
***.Net Application Updater Component****
Want to make your application smart enough to update itself? This
article describes how to do just that. The .NET Application Updater
component included with this article is the same one used to make the
.Net Terrarium game automatically updatable.
