facing problem with ref key word in Managed C++ using In WCF(MSE 5.0)?

[sivaec61]

hi , We developed our application on (Microsoft Enterprise library)MSE 4, then upgraded to MSE5. The problem is that they have removed pointer support in MSE5, which means our code does not support the latest version. we are using managed c++ wrappers and wcf service.
i am getting these exceptions when i am trying run the service.

i am suspecting this problem because of ref key word in Managed c++. please help me how to use alternative approach for ref implementation in our service

Thanks in advance.....
