Cannot connect with Dynamics CRM (System.Security.SecurityException)

Posted on by 42

I'm trying to fix the following problem with my asp.net page. Basically, the application server is configured to .net trust level = medium and I can't change this configuration second the policy of the company.

IIS Configuration

Because of this, I can't connect with dynamics crm with the tooling connector for example. Is there other option of connection to solve this problem?

Discription error

CONNECTION CODE

private static IOrganizationService GetCrmConnection()

    {
        var connectionString = ConfigurationManager.ConnectionStrings["CRMOnlineConn"].ConnectionString;

        // Connect to the CRM web service using a connection string.
        var conn = new CrmServiceClient(connectionString);

        // Cast the proxy client to the IOrganizationService interface.
        var orgService = conn.OrganizationWebProxyClient ?? (IOrganizationService)conn.OrganizationServiceProxy;

        return orgService;
    }
