Fail to post blog for Linux

[MFunction96]

I published the blog and deployed it for CentOS with nginx. I could not post my blog. There is nothing saved in wwwroot\Posts or wwwroot\Drafts folder after I posted my blog.
I guess there are at least one bugs in BlogDataStore.cs, just like the following issues:
\\ is not a path separator for Linux (and maybe Mac)
Cross-Compatability (Windows, Linux, Mac)
