icontrol exception error

Actually we figure the problem out now we manage to come our main point which is creating a NEW ROLE like User_role_test and give some spesific permission to this role via ICONTROL? Is that possible? At first stage we write a new role in Management.Usermanagement.wdsl and generate "ManagementUsermanagement.cs" through wdsl.exe file. Now we want give some permission to this role and deploy all these changes to real F5 machine. We just begin to make something with F5 and Icontol etc. so if the questions are so simple and stupid, sorry in advance.. Thanks a lot
