Security exception when launching c# app from network location

Hi, i have a very small utilty app written in c# that works fine on my local machine but if i put it on a network drive and try to run it from there i get the following securityException..

Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Anyone know why and how i can fix it?

Thanks!

+3  A: 

This is default behaviour for earlier .NET versions. It was 'fixed' in 3.5 SP1. Here is a link.

If you need to use an earlier version, the only solution is to adjust the trustlevel of the assembly (on each PC that uses it). Usually no fun.

Really, a bug? or more a CAS feature?

It was a design 'feature'. The default policies are changed now (3.5SP1 and 4.x). See the link.

CAS feature. The default setting for network locations was changed in 3.5 SP1.

Thank you all for these precisions (the promised +1 :-) )
