Allight guys, I am new to .Net framework.
I have tried to find a good documentation about .Net security but no luck so
far.
If anybody could give me some pointer where to read about .Net security in
regards to coding, please let me know.

The following code is so simple but gave error about .Net security.
I hope that someone could help me out on this and how to setup the .Net
security to make this simple code to work.
Otherwise, I'll just ditch .Net and C# altogether and stay with good ol C++
and WIN32 API.

using System;
using System.Management;
class MainClass
{
public static void Main(string[] args)
{
ManagementObjectSearcher query1 = new ManagementObjectSearcher("SELECT *
FROM Win32_OperatingSystem") ;
}
}

Here is the error that I've got when trying to run this program:

Unhandled Exception: System.Security.SecurityException: Security error.
   at MainClass.Main(String[] args)

The granted set of the failing assembly was:
