I managed to fix the issue, which I encountered on 4.5.3f3 building for Windows 8 Store.

First, I tried building for WP8, and encounter an error due to a use of StreamReader with a string constructor, which is not supported for the platform. That gave me an idea...

I switched back to W8, and my Player Settings -> Publishing Settings -> Compilation Settings were either "None" or "Use Net Core Partially". I done this a while back due to issues I had with a plug-in earlier in testing. Setting this field to "Use Net Core" and building revealed a bunch of errors with code using incompatible interfaces with Windows Store .NET Framework. These included the StreamRead issue above, and using XmlDocument.SelectNodes() and System.Array.AsReadOnly().

So I updated to code to not use those incompatible interfaces - and the error is gone! With the removal from our code of the 3 unsupported Windows Phone and Windows 8 interfaces, the problem was completely eliminated.

It would be nice if these errors could be displayed during editor Unity runs when the platform is selected, rather than just at player build time, but at least this cleared the error.

i have same prolem with unity Version 4.5.2f1.
