How to determine the CAS for an assembly at runtime

lizet.pena

We have a windows form application that is deployed to several remote
users.

We use a batch file to execute the application.
This batch file is in charge of doing an xcopy of any new files
sitting on the deployment share (Intranet).

The batch file also starts the application.

We've noticed since a week ago the application is behaving differently
if it is called from the batch file or from the command prompt than if
the application is called from windows explorer.

The actual error is in loading some objects from our domain model, the
objects are not instantiated properly when we run the application
using the following line on our batch file

start applicationname.exe

The same application works without problems (objects are instantiated
and do not give null reference errors) when we double click the
executable in windows explorer or use the following line in the batch
file

explorer applicationname.exe

Any comments or suggestions for troubleshooting this are more than
welcome.

Why is the security context different?

TIA

Applications run from explorer are run under the my computer zone which has
full trust. The batch file may not depending on the logged on user on which
it is running. You'd first have to determine if this is even a CAS issue by
turning CAS off on the affected machine (caspol -s off at the sdk command
prompt). If the application runs fine with CAS off, then you'll need to
configure an appropriate CAS policy. If the application does not run, you do
not have a CAS policy issue and you should look elsewhere for the problem.
See if that works.

If the application started failing a week ago, this is likely not a CAS
issue.
