Creating OrganizationServiceProxy in CRM2011 Plugin

Question

I have created a plugin and it was registered successfully (Sandbox Isolation Mode).

Inside Plugin execution, I want to create an object of OrganizationServiceProxy, which is using another CRM details. Using the code below:

Uri oUri = new Uri("https://yourorg.api.crm5.dynamics.com/XRMServices/2011/Organization.svc");
            //** Your client credentials 
            ClientCredentials clientCredentials = new ClientCredentials();
            clientCredentials.UserName.UserName = "YourAccount.onmicrosoft.com";
            clientCredentials.UserName.Password = "YourAdminPassword";

            //Create your Organization Service Proxy
            OrganizationServiceProxy _serviceProxy = new OrganizationServiceProxy(
                oUri,
                null,
                clientCredentials,
                null);

I am getting Security Exception:

System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Searched for the same issue but not working, Please suggest.

Taking a long shot here: sandbox plugins have restricted access to localhost (loopback). Are you running you CRM org on same server as the one you are trying to connect? — MarioZG
I am using my plugin on Online CRM and try to connect another Online CRM. Any idea? — Anil P

What version of .NET are you building this in ?

check out these links:

This error is usually caused by some process that doesn't have enough permissions to run. I had this issue before and it solved my problem.

I basically used the new AddFullTrustModuleInSandboxAppDomain method. (check links for more info)

Where exactly do you get this error? When trying to create the proxy ? Or when the plugin is trying to do something (create a report, .. ) ?
