I was trying to add support for sample weights in the XGBoost project in SharpLearning, related to this issue: mdabros/SharpLearning#82

However, it seems that the current DMatrix implementation in XGBoost.Net does not support setting the sample weights. This can be done via the python wrapper for instance, see this example: https://github.com/dmlc/xgboost/blob/master/demo/kaggle-higgs/higgs-numpy.py#L28

Would it be possible to add sample weight support to the DMatrix in XGBoost.Net?

Best regards
Mads
