Xamarin Partnership 2015 Cengage Learning Computing Conference11

Xamarin Partnership  Little Xamarin history  Sponsor Mono community  Xamarin already produces a cross-platform open source.NET framework based on C#  Making it easier to add Xamarin tools to support iOS and Android development alongside Windows apps 2015 Cengage Learning Computing Conference12

New Visual Studio Enhancements  No major chances to new editor  Menus now appear in Title Case style instead of all capitals  Windows touch gestures now supported  New project type templates  Cross platform Development  Visual Studio Emulator for Android  Empty shared project template 2015 Cengage Learning Computing Conference13

New Visual Studio Enhancements  Debugging Tools  New Breakpoint Settings Window  PerfTips (tooltips with performance information)  Few new code editor user interface editing tools  Window layouts  Quick action light bulb icon  Colorized tooltips  Simplified rename  Enhanced Peek Definition 2015 Cengage Learning Computing Conference14

Simplified Rename 2015 Cengage Learning Computing Conference28

Enhanced Peek Definition 2015 Cengage Learning Computing Conference29 Bring definition of method or class into file

Enhanced Peek Definition  Peek released as part of Visual Studio Cengage Learning Computing Conference30

C# 6.0 Language Features  Current Language Specification C# 5.0  Released August 2012  No BIG new concepts with 6.0  Auto-properties can have initializers and no longer require setters  Constructors can assign values to read-only properties 2015 Cengage Learning Computing Conference31

C# 6.0 Language Features  Many small features added  Using clauses for static classes bring static members directly into scope  Exception can have filters  New string interpolation  Null conditional operator added 2015 Cengage Learning Computing Conference32

Getter-only Auto-properties 2015 Cengage Learning Computing Conference33

Auto-property Initializers 2015 Cengage Learning Computing Conference34

Assignment to Read-only Auto-properties in Constructors 2015 Cengage Learning Computing Conference35

Static using Statements 2015 Cengage Learning Computing Conference36 Without using static directive, would write Console.Clear( ); inValue = Console.ReadLine( ); Console.WriteLine(ln ); Console.ReadKey( );

Static using Statements  Static Math class has number of static members using static System.Math;  Instead of writing ans = Math.Pow(arg1, 3); with additional using statement, write: ans = Pow(arg, 3); 2015 Cengage Learning Computing Conference37

Exception Filters  Add an if statement to catch clause for a try…catch…finally statement // body of catch clause 2015 Cengage Learning Computing Conference38

String Interpolation  Previously would have written: return String.Format("{0} {1}\nAmt: {2 :F2}", first, last, amt); 2015 Cengage Learning Computing Conference39

Null Propagating Operator ?.  Saves you from writing lots of if statements 2015 Cengage Learning Computing Conference40

 Available for fall classes  Targets C# 6.0 with Visual Studio Cengage Learning Computing Conference41

Resources  Languages features in C# 6 and VB features-in-C%23-6-and-VB-14 features-in-C%23-6-and-VB-14  VS2015 Preview features – preview-vs.aspx preview-vs.aspx  Barbara Doyle, Jacksonville University Cengage Learning Computing Conference42

Summing up!  New Visual Studio release anticipated Late Spring/Summer 2015  Free Community Edition  Heavy emphasis on cross-platform development opportunities  Xamarin partnership  Free student access with registration  No major enhancements with VS 2015 or C# 6.0  Everything is still subject to change…still a preview after all 2015 Cengage Learning Computing Conference43
