Agenda• What's new today?• Why Visual Studio?• Cross Platform Apps• Mobile Development

Strategy• Tools• Xamarin• Visual C++• Cordova

More Platforms = More Opportunities

• Mobile users want to use same applicationacross devices

• Developers want to target many platforms

Xamarin & Visual Studio

.NET and XamarinShare app logic across platforms• Native apps for Windows, iOS and

Android devices using .NET• Most productive and powerful platform

for creating native applications• Maximize code reuse with Universal

Projects & Portable Class Libraries

100% APIs exposed• Everything you can do in xCode or ADT

you can do with Visual Studio
