James Montemagno walks you through how Xamarin for Visual Studio 2017 makes it even easier to deliver fully native Android, iOS, and UWP apps from a single C# codebase. You'll learn what's new, including: the Xamarin Inspector and Profiler, new language features in C# 7, and how Visual Studio 2017 streamlines mobile development for .NET developers everywhere.

12. Xamarin: Anything you can do in Objective-C,
Swift, or Java, you can do in C# and Visual Studio
• Native user interface
• High-fidelity API access
• Native performance

13. Shared C# logic

System.Data System.Windows System.Numerics System.Core System.ServiceModel
System.Net System System.IO System.Linq System.Xml
C#

18. Android – 100% API coverage

System.Data System.Windows System.Numerics System.Core System.ServiceModel
System.Net System System.IO System.Linq System.Xml

C#

20. Native performance
Xamarin.iOS does full Ahead Of Time
(AOT) compilation to produce an ARM
binary for Apple’s App Store.
Xamarin.Android takes advantage
of Just In Time (JIT) compilation on
the Android device.

26. Trends
Software development is a team sport
Agile & DevOps change the flow
Individual productivity still matters

27. <//>
public async
Task<int>
{int x = await task;
Development flows left to right and repeats

28. We can do better
Tighten the cycle
Catch issues before check-in
Identify issues in production

29. <//>
Continuous integration + real-time experiences = shift left
public async
Task<int>
{int x = await task;

30. <//>
public async
Task<int>
{int x = await task;

31. Edit and continue – pulled debugging into the edit/build cycle
<//>
public async
Task<int>
{int x = await task;

32. <//>
public async
Task<int>
{int x = await task;

33. Live unit testing – pulls quality further into the inner loop
<//>
public async
Task<int>
{int x = await task;

34. <//>
public async
Task<int>
{int x = await task;

35. Live code analysis – immediate feedback loop
<//>
public async
Task<int>
{int x = await task;

37. private static (int Max, int Min) Range(IEnumerable<int> numbers)
{
int min = int.MaxValue;
int max = int.MinValue;
foreach(var n in numbers)
{
min = (n < min) ? n : min;
max = (n > max) ? n : max;
}
return (max, min);
}
var range = Range(numbers);
Or
(int min, int max) = Range(numbers);

38. public static int DiceSum4(IEnumerable<object> values)
{
var sum = 0;
foreach (var item in values)
{
switch (item)
{
case 0: break;
case int val: sum += val; break;
case IEnumerable<object> subList when subList.Any():
sum += DiceSum4(subList);
break;
case IEnumerable<object> subList:
break;
case null:
break;
default:
throw new InvalidOperationException("unknown item type");
}
}
return sum;
