Question on .NET Smart Client Application.

[Q. John Chen]

Group,

Have couple questions on .NET smart clients:

1. The application "is downloaded to the assembly download cache on the
client computer." What if the user "Delete all the temporary internet
files" from the browser. Will the assembly download cache will also be
cleaned up?

2. People is concerned about the security. But my concern is that to
much securinty that cause the application failed to downloaded to the
client's computer. I am make software to the public or unknown user. I
don't want any firewall or security settings block my application or
component.

Please advise.

Thanks in advance.

John

You can implement Smart Client from lot of different ways: for example using
clickonce
(http://msdn.microsoft.com/msdnmag/issues/04/05/clickonce/default.aspx) or
using Updater Application Block
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpag2/html/updaterv2.asp).
If you're using clickonce, the answer to your question is YES: if the user
delete all the temporary internet files the download cache will also be
cleaned up.
If you're using UAB, the answer to your question is NO: you can have a full
control on where your files are (including in the GAC).

2. People is concerned about the security. But my concern is that to
much securinty that cause the application failed to downloaded to the
client's computer. I am make software to the public or unknown user. I
don't want any firewall or security settings block my application or
component.

Clickonce and UAB have not the same security limit.
By the way, your user just need a HTTP access to download your files.
To run your application your user may need more right depending of what you
are doing (file system access, registry, changing system time, ...).

Please advise.

Thanks in advance.

I hope it helps.
