How to do minibatch evaluation using CNTK eval api

I want to use CNTK Evaluation API to give scores for my data. Currently I see there is one by one way of evaluation. I am curious whether the minibatch supported in CNTK evaluation? Where could I find some sample code for it?

I know this was posted long ago but in case someone else ends on this question.

In python there is a direct parallel between using a minibatch in training and evaluation. In training, the .train_minibatch method can be used on a cntk.Trainer object and for evaluation the .test_minibatch method can be used on a cntk.Evaluator object.

See the section "3. Feeding Data Via an Explicit Minibatch Loop" in CNTK_200_GuidedTour for an example.

Evaluation with batch data is supported by the new version of C# Eval API. This page describes how to use the API. And you can find examples here with building instructions.
