Assembly.LoadFrom when offline

[Greg Bacchus]

Hi,
Does anyone know how to get an offline reference to an assembly that has
been downloaded using Assembly.LoadFrom.

E.g. Application downloads the assembly while it in online... next time it
is run it is offline and needs to still use that same assembly.
Assembly.LoadFrom throws an exception.

The downloaded assembly IS cached locally, in the assembly cache,
but how do I reference it from there? I was hoping that it would be
intelligent enough to automatically look in the download cache by itself
when I referenced the web assembly!! (But its not) The advantage with this
is it then
automatically handles trickel deployment. So if that assembly references
another assembly that does not exist, the framework automatically looks in
the referenced location of the first one - on the web. You see this wouldn't
work if I have to make a local reference to the assembly.

Cheers,
Greg

You can't, the problem is this: when you call Assembly.LoadFrom, the loader
has no way of knowing if its cached copy is up to date. So it has to go to
the web server to check if it has changed. If it hasn't it will then run
with the cached copy. Problem is, it still needs to be able to connect to
the web server to detect a change.
You definitely need to use another technology to achieve what you want.
Check the "application updater component", I guess it's exactly what you are
looking for.
