Lessons learned from Building a Visual Studio Shell with UWP
Note: There's a MS Dev Show Episode where @ytechie, @carlschweitzer and I are talking about UWP and the Visual Studio Shell built as part of this post.

Some parts like a DataGrid are available as 3rd-party controls. Other parts like the TreeView are already in development, as you can see in the Windows Dev Platform Backlog. That backlog shows that Microsoft is working on a TreeView, which is awesome! And I'm pretty sure, at some point in the future we'll also get a DataGrid. This was the case for WPF and also for Silverlight. But let's see, the future will tell us and for today we've great 3rd-party DataGrids. But what else is required to build a classic desktop application? (more…)
