Gunnar Peipman discusses what's new in ASP.NET vNext. Key updates include support for true side-by-side deployment, a cloud optimized .NET Core runtime that takes up only 11MB, and ASP.NET components being merged into a single framework. ASP.NET vNext apps are designed to be cloud ready. The new K runtime features multiple layers including the CLR native host and managed entry point. KVM and KPM are also introduced as tools for managing the K runtime and packages.

• Walks the dependencies in the project and builds up the closure of dependencies
• Adds ILoader => LoaderContainer that can load assemblies from various sources
• Calls the entry point of assembly name given as the next argument given to KLR.exe
Layer 3
Application Host
• Developer’s application code when running on the application host
Layer 4
Application
