According to the
LDS Tools for Windows Phone development page on the wiki, the project is inactive. It hasn't received as much attention as iOS and Android tools, in large part because the market is so much smaller. I know it can be frustrating when you're using an application that doesn't receive a lot of attention; it's clearly important to you. But the Church has limited resources for maintaining and supporting applications, and there has never been much of a community support group for that platform.
As you can read in the thread
Any efforts for Windows 8 applications?, some plans are underway for Windows 8, but no specifics have been announced yet.
Questions that can benefit the larger community should be asked in a public forum, not a private message.
