That doesn't apply here. This is a strategic purchase for Microsoft. They have no competing technology. That was in reference to standards. Microsoft wanted to turn open standards into proprietary standards to drive people toward their products.

...Xamarin studio isn't a competitor to Visual Studio?

That's all I know that Xamarin makes, so I think this article is going a bit over my head, but it'll be a shame if I suddenly need a Microsoft account to use it. I do like diversity in my language tooling.

Xamarin is not about Xamarin Studio. It's about the iOS and Android runtimes. Thanks to its ability to take full advantage of AOT compilation, the performance difference is staggering compared to Mono. Also it needs to JIT in less situations, which is a big plus on iOS since JITing is prohibited on that platform "for security reasons".

It is bad enough that you have to keep a Mac around with XCode on it to build any iOS apps now.

Last I checked, that was just a forked and rebranded Mono Develop with Xamarin's main product line (iOS and Android support for .NET) bundled in.

Visual Studio doesn't run on Mac OS to make iOS apps, VS Code is still only an editor not an IDE. So Xamarin could be very useful for MS.

I'm not debating that Xamarins products are useful to Microsoft, I'm questioning the assertion that they haven't just consumed a competitor.

Considering Microsoft has no Mac IDE, I'm not sure how Xamarin could be considered a competitor.

...because Visual Studio is a C#/C++ IDE that works on Windows, and Xamarin Studio is also a C#/C++ IDE that works on Windows?

Xamarin Studio is a swiss army knife. I don't know about your use case, but I use it under the name Monodevelop on linux (not really sure what that association is) and as Xamarin studio on windows. For my use case, it's a C# and C++ IDE for desktop development, same as visual studio.

It's certainly not a MacOS only product, it supports all three platforms including windows.

Have you ever used .NET on its own platform?

Mono only supports a subset of the whole stack.

No sane .NET developer would use Mono on Windows, its purpose is .NET portability to other OSes.

Ask them about Alan Truing - he kept his work secret so should have had his career ruined by the likes of you.

Poor guy. His name autocorrects to one of the best-known names in computing.
