On Tuesday, Nathan Herring blogged that he was leaving the CoreCLR team to work on the Mac version of the MiniCLR that will make up a part of WPF/E. While the announcement is relatively small, Bruce McLeod noted that this essentially confirms some of the .NET runtime will be ported to Mac OSX.
I remain a little bit skeptical about what WPF/E will look like in the end, and while this announcement does show that there is some support within Microsoft for WPF/E and perhaps down the road a full-blown implementation of WPF for Mac, I'm not holding my breath. In the past, Microsoft has only supported Mac just enough to get people "hooked" and then brining them over to the native Microsoft technology. Will WPF/E be any different?
