solution

The issue is that you might be running an old version of the framework. Try going to the root (

project.json

) location of your runnable project and in a

Command Prompt

type:

dotnet run

D:\Git\Docs\aspnetcore\fundamentals\logging\sample\src\TodoApi>dotnet run
Project TodoApi (.NETCoreApp,Version=v1.0) was previously compiled. Skipping compilation.

The specified framework 'Microsoft.NETCore.App', version '1.1.0' was not found.

  - Check application dependencies and target a framework version installed at:

      C:\Program Files\dotnet\shared\Microsoft.NETCore.App

  - The following versions are installed:

      1.0.0

      1.0.1

  - Alternatively, install the framework version '1.1.0'.
