Application Domain Tutorial Part 1

CONFIGURING APPLICATION DOMAINS
------------------------------------------------

We need configure application domains to create customized environments for the assemblies.If you run an assembly with full trust access then one: There is no point of running that assembly in an application domain and Two: Your application domain becomes vulnerable for any security risks.

So one way to limit access privileges to the assemblies is by using EVIDENCE. Evidence is the access privileges information of the assembly which is gathered by runtime.You need add System.Security.Policy namespace to be able to create Evidence for an assembly.In our previous example we ran an assembly in an application domain using ExecuteAssembly Method.Now in this example, we will use ExecuteAssemblyByName method to run an assembly with access privileges limited to local computer.Remember you can do the same using ExecuteAssembly Method as well.

        static void Main(string[] args)
        {
            object[] hEvidence = {new Zone(System.Security.SecurityZone.MyComputer) };
            Evidence AppEvidence = new Evidence(hEvidence,null);
            AppDomain d = AppDomain.CreateDomain("HelloWorldDomain");
  
            d.ExecuteAssemblyByName("HelloWorld",AppEvidence);
            AppDomain.Unload(d);
        }
    }
}
