Being able to run C# programs on on Android and iOS sounds good, but Xamarin was never able to make a go of it. So, why should things change now? The...contrarian view

I'm excited to give Xamarin a try, but I'm a bit skeptical. I haven't had any need to write mobile apps, but my curiosity got to me recently. Being a .Net developer for over a decade makes me cringe at wasting time learning new languages that I will not use. Thus, I watched a Pluralsight video on Xamarin and felt it over complicated things. I almost feel that it would be easier write a secure web service and call it from separate IOS and Android user interfaces.
I see Xamarin as more of a marketing ploy than anything else. It is Microsoft promise to business people that we'll save you time and money doing it our way. Hopefully my skepticism is wrong.

I felt the same way. I had investigated other ways to build mobile apps too (cordova / phoneGap).
None of it worked well.
I finally started learning Android Java and though I'm an old C++ dev who migrated to C# (over 10 years ago), I find the Google Android Java stuff to be done very nicely. There's a lot of support out there too.
The new Android Studio is quite a bit nicer than Eclipse (IMO) too.

I'll have to take a closer look later.
I will also have to set up a system specifcally to run it because I will not have the Java SDK on my daily system.
To bad the new book is only on Kindle unless i missed something. I don't own one nor plan on getting one at the moment.

Thanks for the kind reply.
I will also be releasing the book as a bound and printed book 6x9 format using CreateSpace.com (amazon.com publishing arm) and I am guaranteeing to keep my price at $9.99. My book is at 270 pages right now and looks like it will be somewhere in the neighborhood of 500-600 pages and my aim is to keep the price very low. I'll only make about $1.00 from each copy, but low price is important to me.
I think the price of tech books is outlandish.
I am releasing the Kindle version for $2.99 and they allow the pre-release page but so far I don't have that ability on the print book. The print book will release on April 1, 2016 also.

Ok thanks for the reply, I'll have to look into it more when I get time for the learning curve.
And have time to set up another system.
I learn best by doing.

Using Xamarin here and it's awesome! 
Though I was so confused the first project! 
Mostly using Xamarin forms... still confusing when with Xamarin android specific .axaml / Native Android UI files! 
4 project going with it so far.. going strong!

I've written Android apps with Java and Xamarin. Without a doubt, Xamarin is superior in every way, from development to deployment, even battery use is lower.
Having said that, Xamarin's pricing is irrational and Microsoft will need to address it asap.

Thank you Franc and SuperLloyd. I appreciate your hands-on opinion and will look to learn more about it.

imho, a very poor article, a collection of hearsay and rumors by someone who has, evidently, never actually used Xamarin tools to create apps, and, the article does not consider the possibility that Microsoft acquired Xamarin in order to take it off the market (yes, that's unlikely, given that MS killed their "Android Bridge to Nowhere," and is making noises that Xamarin will replace that).
Note the frequency with which the author disclaims his statements by using "sounds ... like."
Consider the hype around the Nokia acquisition, and where Nokia is now.
I do hope they turn loose Miguel de Icaza (un-muzzled) in the halls of Redmond; he's outspoken, and forceful.

Sure sounds like that to me

Sounds like a possible Microsoft hater to me.
Or just an idiot.
What do you get when you cross a joke with a rhetorical question?
The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism.
Do questions with multiple question marks annoy you???

Seems like a pretty pointless tool seeing as you still have to re-write the UI code twice, as the the widget libraries for iOS and Android are different.
Plus, I heard that starting up the emulator for Android is so slow it's not even usable.

Microsoft has made security a priority throughout every aspect of its business and many people would argue is a necessity for a technology behemoth of their caliber. Microsoft and security in one sentence. Those used to be very different sentences.

If you squint, you can see how the word “click” might look inappropriate. But Apple’s too prim and proper for that. Why yes, I am juvenile. Why do you ask?

The funny thing is they don't do this on the Canadian version (yet they do on the Australian version).
I wonder what Jonny has to say about it all?
