How do I avoid MSE5.0 problems with ref key word in interfaces and operation contracts

C#3.5

Hi All ,

Currently in our C#.net project, we are using MsE4.0 .It is working fine. In the interfaces (service contracts/operation Contracts) we have lot of "ref" keywords used. Now we would like to move to MsE5.0. It is not accepting "ref" keywords in interfaces(operation contracts)
Thus creating problems.

Could you please let me know if there are any good alternatives (third party tools) to MsE5.0 , that can handle/tackle the problems caused by having "ref" keywords in the interfaces(operation contracts) gracefully.

I know that Microsoft is giving a patch for this , but i am not sure that MS supports this in future MSE 6.0

Appreciate your help.

Thanks,
Sudhakar
