Coding assignments with dotnet interactive and vs-code live share
Thanks to new .NET interactive notebooks is now possible to do live (potentially polyglot as well!) coding assignments, having all the test in a single page, with a linear story-line for both the interviewers and the candidate.
Unlike jupyter notebooks, they don’t require a separate notebook kernel but they just run on top of .net interactive, installed as a global .net tool (the vscode extension will auto-install it for you)
I think this is pretty awesome. ☯️
Here is just an example using C# language, in this very simple example a candidate would have to run the code and make the test green…
The first thing the candidate must check is the DI container error, it’s clear a service must be registered, e.g. adding the line:
var services = host.Services;services.AddTransient<MyClass>(); //<<<<<<<<< was missing
In this example, the candidate has to further fix the MakeFive function to return correctly the number 5, and make the test go green.
public int MakeFive() => 5;It’s just a dumbojumbo example of how this feature/technique could be used in a simple yet prolific manner.
Why not trying your own notebook now, in this next 5 minutes?
Have a great day!
