There are rumors that Microsoft is considering the purchase of Xamarin [1]. And now Microsoft is now previewing their .NET AOT compiler for X64 and ARM. I see great things in C#/.NET's future in mobile and cross platform development.
On another note, I wonder if Microsoft addressed the inherent limitations of AOT in C# [2]. I wonder if it's a compile-time error, or if that segment of code is interpreted. I doubt it's interpreted, as that's a giant perf loss.
Still rumor and I don't expect to see anything on that front for some time. Why buy the cow when the milk is free, not like Xamarin is flirting with enabling Java on iOS or something - they are sold out to C#/F# so Microsoft is reaping the benefit.
More evidence, Xamarin announced their Evolve conference dates, times and prices and when it goes on sale - if Microsoft were buying them they would hold off on letting several thousand people spend thousands of dollars for a dev conference that would later be tantamount to a bait and switch.
"Microsoft is in the final stages of negotiations that could lead to either an acquisition or major investment in Xamarin, sources with knowledge of the discussions told CRN recently."
The article is from march 17th and there doesn't seem to be anything newer.
I'm also very excited about the idea of getting back into C# again. I always loved the language, but moved away from the .NET stack. Here's hoping.
