Mechanical transformation from out parameters to tuples.

gistfile1.cs

    public class SdkClass
    {
        public int GetInfo(string param1, out string outParam)
        {
            // ...
            var errorCode = 1;
            outParam = "MyInfo";
            return errorCode;
        }
    }

    // This transformation is very mechanical, but allows to access both function results in a pipelined manner.
    // I think I would not write tests for this class, but I would consider to codegen this code if you use it a lot.
    public class TupledSdkClass
    {
        readonly SdkClass _sdk;

        public TupledSdkClass(SdkClass sdk)
        {
            _sdk = sdk;
        }

        public Tuple<int, string> GetInfo(string param1)
        {
            string outParam;
            var result = _sdk.GetInfo(param1, out outParam);
            return Tuple.Create(result, outParam);
        }
    }
