Would like to open the code in Visual Studio 2015

Hi Asido,

OK - so I've started using your library; and would like to make some improvements.

But I need Visual Studio 2015 installed on my computer.

Is there a way I can open the project in VS 2015..?

Distribute via nuget

Looks like a cool project that I'm keen to have a play with. Thanks for your hard work on it!

EPubwriter

Thank you for this great project. Do you have plans to still work on the EPubWriter?

Exception parsing epub 3.0.1 with roman numeral page numbers

I am trying to parse an EPUB 3.0.1 which successfully validates using EpubCheck version 4.0.2.

EpubReader.Read() throws on line 41 of NcxReader.cs.

Value = (int?)elem.Attribute(NcxPageTarget.Attributes.Value)

I cannot share the book but the content of the element is as follows. As you can see, the value of the attribute is "i" and not an integer.

<pageTarget id="navPoint43" type="normal" value="i" xmlns="http://www.daisy.org/z3986/2005/ncx/">
  <navLabel>
    <text>i</text>
  </navLabel>
  <content src="xhtml/02_Title_Page.xhtml#page_i" />
</pageTarget>

Stack trace:

The books parses without exceptions if NcxPageTarget.Value is changed to a string.

This one ebook doesn't read...

This is somewhat random ebook I grabbed in order to test your library in my new ebook reader. So far, most ebooks area read by your library perfectly (testing includes books from the UN, USDA, NASA, Project Gutenberg and archive.org, plus others as I find them)

Other ebook readers (Nook and Freda) can read it OK.
