While this is likely on the positive feedback from developers post-Elopocalypse and likely only a very small subset of the developers that are part of Forum Nokia but the fact of the matter is some developers are excited by the promise that Windows Phone on Nokia is bringing. In any case it’s probably important to note that Visual Studio and .NET are a core part of many computer science curricula.
In essence, there are more programmers and developers coming out of school knowing how to make apps and develop for WP7 than there likely would ever be Symbian C++ developers. Furthermore, the fact that Microsoft’s development tools are known the world over as some of the best available makes the decision to use Silverlight and .Net as opposed to Qt an even better one given the breadth of familiarity in the developer community with those frameworks. That is not however, to say that Qt isn’t good in its own right, but that adoption of Windows Phone 7 and the frameworks associated make more sense from a technical standpoint than porting Qt to that platform.
