Can I run a new process from a medium-trust ASP.NET application?

Question

I'm building an ASP.NET MVC site where I want to use OpenSTV to conduct polls. To run results through OpenSTV, I'd have to run the executable. Is that allowed from a medium-trust ASP.NET application?

Answer 1

You can't instantiate a System.Diagnostics.Process object unless you're running at FullTrust.

If you examine the attributes decorating the class you'll see the demand for FullTrust:

Process Class (MSDN)

[PermissionSetAttribute(SecurityAction.InheritanceDemand, Name = "FullTrust")]
[HostProtectionAttribute(SecurityAction.LinkDemand, 
        SharedState = true, Synchronization = true, 
    ExternalProcessMgmt = true, SelfAffectingProcessMgmt = true)]
[PermissionSetAttribute(SecurityAction.LinkDemand, Name = "FullTrust")]
public class Process : Component
