You want to write mobile apps, but you don’t want to write the same code four times over. You want cross-platform apps, but you don’t want to sacrifice the native speed and power. You want to create native iOS, Android, Windows Phone, and Windows 8 apps, and you want it all while maximizing code reuse and harnessing the power and simplicity of C#. You want four native platforms, but you want one codebase. Of course you do. You want Xamarin.

what does an app cost?
mobile development approaches
silos• build app multiple times• multiple teams• multiple code bases• different toolsets
write once, run anywhere• lowest common denominator• browser fragmentation• developing and designing for one platform
xamarin‘s unique approach• native user interface• native performance• shared code across platforms• c# and .net framework• full api coverage
why C#?
C# is awesome• async/await• linq• xml + xdocument• event handling, delgates, lambdas• generics
+ (NSDate *) stripTime:(NSDate *) date { NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [gregorian components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit) fromDate:date];
date = [gregorian dateFromComponents:components];
[gregorian release];
return date; }
var newDate = date.Date;
NSString *string = @“ spaces in front and at the end “;NSString *trimmedString = [string stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]];
var trimmedString = “ spaces in front and at the end “.Trim();
