DEMO: .NET Standard across the world

Visual Studio 2017 – RTM March 7 Improved performance, new install experience Faster navigation Code style configuration and enforcement Live Unit Testing IntelliSense improvements New exception helper More refactorings and quick fixes C# 7.0

Coming in Visual Studio 2017 Update 3 Additional polish to navigation and IntelliSense .NET Core support for Live Unit Testing Code style enforcement on builds More live diagnostics on API design, security, etc. Even more refactorings and quick fixes C# 7.1

DEMO: Live unit testing

.NET Core and Visual Studio for Mac Provide the SAME experience across Windows and Mac Sharing components with Visual Studio .NET Core Project Templates HTML, CSS, JSON editors Backend debugger Azure Publish infrastructure Future JavaScript, Razor editors

.NET Core and Visual Studio for Mac Full .NET Core Tooling including round tripping between Windows and Mac Docker Containers with debugging Publish to App Service Publish to App Service Containers Azure Functions

DEMO: Visual Studio for Mac

Azure diagnostics Should be simple From the Portal From Visual Studio No modifications to your app No republishing of your app From the Portal Enable/Disable analytics and diagnostics See common crashes and performance problems including seeing code From Visual Studio See analytics data from portal in real time Use “snap points” to debug a running application

DEMO: Azure Application Insights

Docker For build-time or for runtime On Windows or on Linux Choose your base image And upgrade it as necessary Features coming to .NET for coordinating multiple images For example, health checks, service discovery Works in Visual Studio, Visual Studio for Mac, and VS Code Debug remotely using VS Azure supports Windows and Linux containers Azure Container Service for Linux (Windows coming) Service Fabric for Windows (Linux coming)

DEMO: Docker with Visual Studio

Summary .NET Standard for productivity .NET Core for fast-paced, cross-platform, standalone/SxS dev/deploy Visual Studio 2017 Live Unit Testing and C# Visual Studio for Mac for collaboration Azure for simplified app management and diagnostics Docker for reliable deployment, easy configuration, and scale
