New Office has decided the faith of Xamarin

It took “them” 5 years to prove me right :)

Xamarin Sunset

Microsoft sunsets Xamarin toolkit

Seriously. Why so long? I assume to keep the shareholders happy, about dubious investment. Or someone indeed believed in “Xamarain”.

Of course (even) I was talking rubbish about Office development being related to the faith of Xamarin. Although, rest assured, in the dark ages of Microsoft there was a serious semi-hidden belief .NET platform will be the foundation of everything.

Xamarin is now free in Visual Studio

Before you jump to conclusions please consider this:  By this move, Microsoft is not using Xamarin, Microsoft is giving it away. And that is the core logic here.

The reason Microsoft has been able to keep both Android and iOS versions identical is thanks to a new cross-platform approach to the codebase of Office. “It has required us to be great at writing platform code for Android, code for iOS, and code for Windows,” says Atalla. All of that effort has been put together into a single platform so Microsoft can share code across iOS, Android, and Windows. The benefit is faster updates and more features for Office users. “Over the past year, we’ve had 150 different updates to Office applications across all platforms,” says Atalla. “We’re moving very very quickly in adding capability and adding functionality.”

They are talking about Xamarin here surely? Well… no. They do not talk about Xamarin.

This is description of pure C++, MSFT multi platform foundation made for next wave of Office Apps. Put this together with already brewing confusion about Xamarin vs MSFT, and you do not need a lot of spice for a very juicy gossip.

Yes here they/we/whoever are not talking common multiplatform runtime, that is true. But, I think Xamarin has lost. MSFT has decided to implement a common multi-platform platform (sic) itself, vs buying Xamarin or working with Xamarin or some such long-winded exercise. Microsoft solution is currently not a single monolithic executable providing a common runtime that is true. And significant. For me this means they have finally concluded that is not the best approach. Especially when needing and using native UI.

In essence now after the next Office wave is shaping up publicly, it is clear MSFT does not need Xamarin. I do not think MSFT will be against Xamarin efforts, quite the contrary, but still, Xamarin will not be the foundation of any MSFT-made, cross-platform code.

End of story? Not yet. The end of Xamarin’s story is detailed here. It is called “AirSpace”. The new Microsoft Cross-Platform Architecture.

It is hard to imagine this will be used just for Office apps.

It is not entirely clear is this architecture implemented as a “toolchain” or a “platform”. I think this is a combination of both.  The “thing” spills out common modules, yes, but they are compiled in different binaries for different platforms.  (platforms are listed on the left).

As the UI parts are definitely different since native UI’s are used, it is even less clear (from this picture) what is this “AirSpace Frontend”. Probably some abstractions (and tools)  to ease up the multi-platform UI building.

But one (key) fact is certain here: Microsoft has left common run-time architecture behind.  Above is a “toolchain” and “common” platform. But for multi-platform software production. Not for providing common run-time.

In case you have not noticed, Office and other Microsoft flagship products have never been running on top of CLR. Or implemented using .NET, C#, and such.

This all seems to me as an EOL (end of the line) for Common Language Runtime too.  In any case, end of the story for Xamarin, foster-child.

(For the continuation of this speculation please proceed here)

Yet another merciless nail into the Mono coffin: Microsoft takes lid off .Net Common Language Runtime sauce
