No XLIFF language files were found. After updating to MAT 3.1 <p>I have a Windows Store project that I've been developing for quite some time. The Multilingual App Toolkit has been amazing so far. Recently I updated to version 3.1. Unfortunately, this caused the build process to not process my <code>.xlf</code> files that I've been using for a year now.</p> <p>Based on <a href="http://blog.giovannimodica.com/post/how-to-use-the-multilingual-app-toolkit-mat-in-a-portable-class-library-pcl-project" rel="nofollow">this entry</a> I took a look at my project file. The resources were defined similarly to how the blog entry suggested they <em>should</em> be. Similar to this:</p> <pre><code>&lt;ItemGroup&gt; &lt;XliffResource Include="MultilingualResources\MyProject.WinRT_ar.xlf" /&gt; &lt;XliffResource Include="MultilingualResources\MyProject.WinRT_bg-BG.xlf" /&gt; &lt;XliffResource Include="MultilingualResources\MyProject.WinRT_ca-ES.xlf" /&gt; ... </code></pre> <p>I tried many things, including adding <code>&lt;Generator&gt;</code> tags. None of it seemed to be working. How can I get the project to see my <code>.xlf</code>s?</p>
