The digest of interesting materials for the mobile developer # 147 (March 28 - April 3)

Unexpectedly, the main event of the week was the Build conference from Microsoft - Xamarin was announced free of charge, Xbox was available for development, new recognition APIs, bots and more.

Mobile OCR. How it all began

The transfer of OCR technologies (optical recognition technologies) from a PC to mobile devices has been discussed, perhaps, from the moment they appeared. Back in the late 90s, when smart devices could be counted on the fingers, we thought about creating a program that extracts data from a business card, the Business Card Reader, or BCR for short.

Xamarin is now free

On the second day of the conference, Vice President Scott Guthrie said: Xamarin cross-platform solutions will be integrated into Visual Studio and will be free, even in Community Edition.
