Issues in compiling with Visual Studio 2013 about cntk

[frankseide]

Please use VS Update 5. That is the version we use, and it is know that some older versions of 2013 do not yet have the array constructor that is causing the error.

Some projects don't compile under Visual Studio 2013 without changes

1 Filecpp isn't included in project HTKMLFReader
It is easy to fix Just add the missing file to the project

2 Initialization of array
The errors happen at several places, eg, in file TensorViewcpp
void TensorView::DoUnaryOpOf(ElemType beta, const TensorView& a, ElemType alpha, ElementWiseOperator op)
{

PrepareTensorOperands<ElemType, 2>(array<TensorShape, 2>{aGetShape(), GetShape()}, offsets, regularOpDims, regularStrides, reducingOpDims, reducingStrides);

}

I got the following error

My work-around solution is to add an additional pair of '{' and '}' for the array as
PrepareTensorOperands(array{ { aGetShape(), GetShape()} } , offsets, regularOpDims, regularStrides, reducingOpDims, reducingStrides);

Anyone knows what is the root cause of this compiling error?

Yes, the compiling errors are gone after installing Update 5. Thank you very much!
