Web Service ?

Recently, I developed a web service on my dev box (XP SP2). On another
machine, I developed a console app that uses a method in the web service that
just returns an integer. Everything works fine in the console app.

However, if I put the same code in a code behind application for Excel 2003
using VSTO 2003, I get the following error:

System.Security.SecurityException: Request for the permission of type
System.Net.WebPermission, System, bla bla bla ... failed.

Why does the code work in a console app and not in my VSTO Excel App? More
importantly, how do I get the VSTO app to work?

Thanks,

Can you run the webservice locally on the same vsto machine and see what
happens? If it runs, you will need to cnfgure VSTO permissions for the
remote site

Peter has a good blog about this...

Basically, a helper assembly is loaded at run-time in order to pass the data
to/from the web service via XML. This assembly doesn't have enough
permission to execute, so you need to grant the assembly permission. He goes
on to say that you can do this by adding a rule to the policy that grants
FullTrust to the GAC path of System.dll.

This can also be done using the mmc .net configuration tool.
