This document provides an overview of .NET Core and discusses getting started, the dotnet command line interface, apps and libraries, current frustrations, converting existing code, building for both .NET 4.5 and .NET Core, and concludes with a thank you. It recommends installing the .NET Core SDK, updating Visual Studio, using the dotnet CLI for building even when using Visual Studio, understanding how console, web, and test projects target frameworks differently than libraries, and dealing with issues like unfinished Visual Studio tooling and lack of NuGet package support for some frameworks.

1. .NET Core in the Real World

2. Getting Started
● Install .NET Core SDK
● Update Visual Studio (if on
Windows)

3. dotnet cli
● Even if you’re using Visual Studio,
the new CLI is very useful!
dotnet new
dotnet restore
dotnet build
dotnet pack

4. Apps and
Libraries
● Console, web, and test projects
target netcoreapp1.0
● Libraries target
netstandard1.X
● Lower = more compatibility
Higher = more features/APIs

5. Current
Frustrations
● Visual Studio tooling is still
unpolished
● Most Nuget packages don’t
support netstandard yet
● Confusion or lack of
documentation online

6. 1. Create a project.json/xproj next
to your csproj
2. Tweak netstandard version
3. Fix errors, repeat
4. Profit!
Converting
Existing Code?
Works fine!

7. Building for both .
NET 4.5 & .NET Core
It’s possible!

8. Demo

9. Thank you!
