<p>I start a .Net server side program on my local workstation, but soon it throws a security exception. I searched the web for answers, but no quick fix was found / worked. I just want to run my program. How do I get rid of the exception? I fully trust the program, because its mine.</p>

<p>Edit: Oh, yes, I do run the program from a mapped folder that is mapped to my own local drive for the sake of clarity of folder structures. Thanks for the answers, I try tomorrow to run it directly from my drive.</p>

<p>Edit: When I use directly my drive, it works.</p>

.NET 3.5 SP1 has better support for running applications on the local intranet.
If you can't target 3.5 SP1, you can map the share you're running the application from to a local drive and
use CasPol to set that mapped drive to a fully trusted location.
