The type or namespace name 'Xml' does not exist in the namespace 'System'

I had a trouble building Castle Core project in DNX.
Here's the build log : https://gist.github.com/uhaciogullari/ce214c172f12eb1fca0c

You will see that most of the errors are about XML classes. I tried every XML package(except the ones about configuration) on the NuGet feed but none of them fixed it.

What am I missing here?

Here's the project file btw : https://github.com/uhaciogullari/Core/blob/core/src/Castle.Core/project.json

Moving the packages from frameworks.dnxcore50.dependencies to dependencies in project file solved the problem.
