Changes in this release:
Added support and configuration options for spell checking any WPF text box within Visual Studio. See the Visual Studio WPF Text Boxes topic for usage notes and for known issues and limitations.
Added support for spell checking PHP files within the Visual Studio text editor when using the PHP Tools for Visual Studio extension. Thanks to Miloslav Beňo of DevSense for the tagger implementation.
Made various adjustments to escape character checking. It is now only performed in C-style language files. When doing solution/project spell checking, it is further limited to only check comments and normal string literals.
Added support for installing the extension in Visual Studio 15 Preview 2.
