Following on from a previous post on using dotnet interactive inside vs code we can dig a little deeper in to some more useful functionality. We all need to consume NuGet packages right? I know I certainly do.
It is entirely possible to pull a package down and starting coding against that package. I use this feature a lot for diagnosing or testing things out with my own OSS library hosted via NuGet.
All you need to do is declare the following inside your C# code block:
#r "nuget: PACKAGE_ID, PACKAGE_VERSION"
So shameless plug time :), here is how I do it with my own library:
#r "nuget: ExpressiveParser, 2.4.0"
Then you are free to start using that package:
var expression = new Expressive.Expression("Pow(2, WeekDay(#today#))"); expression.RegisterFunction("WeekDay", (p, a) => ((DateTime)p.Evaluate(a)).DayOfWeek); Console.WriteLine(expression.Evaluate());
Here you can see it in action, simply hit Ctrl+Return and watch the tool pull the package the first time and then execute the code.
