Importing packages, libraries, and scripts¶

You can load packages into a .NET notebook from NuGet using the following syntax:

#r "nuget:<package name>[,<package version>]"

If you don't provide an explicit package version, the latest available non-preview version will be loaded.

Here's an example:

In [ ]:

#r "nuget:System.Reactive.Linq, 4.1.5"

Now that the package is loaded, we can add some using statements and write some code.

In [ ]:

using System.Reactive;
using System.Reactive.Linq;
using System.Reactive.Concurrency;

var output = display("Counting...");

var sub = Observable
    .Interval(TimeSpan.FromSeconds(.5), CurrentThreadScheduler.Instance)    
    .Take(10) 
    .Subscribe(i => output.Update(i));

If you want to load an assembly that's already on disk, you can do so using this syntax:

#r "<path to .dll>"

You can load a C# script (typically a .csx file) into the notebook using this syntax:

#load "<path to .csx file>"

In [ ]:

#load "something.csx"
