Hi, It's not possible to add comments anywhere except at the start. Steps to reproduce: * open https://github.com/SciSharp/protobuf.Text/blob/master/test/Test/Config/faster_rcnn_resnet101_voc07.config * Append `# This is some comment` * Run tests inside of this repository * Error `Protobuf.Text.InvalidTextProtocolBufferException : Unknown field: #`
