Exception when using .NET Polyglot Notebook due to strong naming

[dibenzepin]

Description

When I make a minimal C#/F# notebook, it fails to render under the cell when the chart is the last variable. However when Chart.Show() is called, it opens fine in a browser window.

Repro steps

1. Download the Polyglot Notebooks extension

2. Make a new .ipynb file

3. Add the following cells:

   --------------------------------- 
   #r "nuget: Plotly.NET.Interactive"
   #r "nuget: Plotly.NET.CSharp"
   ---------------------------------
   let xData' = [ 0. .. 10. ]
   let yData' = [ 0. .. 10. ]
   Chart.Point(xData', yData')
   ---------------------------------
   using Plotly.NET.CSharp;
   
   Chart.Point<int, int, string>(
       x: Enumerable.Range(0,11),
       y: Enumerable.Range(0,11)
   )
   

Expected behavior

The chart is rendered under both cells.

Actual behavior

An exception is thrown:

Known workarounds

Don't display the cell output in the cell, call .Show() to open it in a browser

Hey @poopsicles thanks for reporting this.

I can not reproduce this issue, at least not on windows. You seem to be mixing F# and C# cells, but have no dependency loading cell for both (your first cell can only work for one, C# or F#)

However, i tried all permutations that are expected to work, and all of them produce the desired chart:

What version of the extension are you using?

Hey @kMutagene, thanks for the quick response.

Yeah I saw that the library was somewhat F#-first, that's why I tried to do it in both languages. I'll see if I can try and get the issue on some of my other friends' devices, they use the whole spectrum (macOS, Windows, Fedora) so that I can see if it's just a me problem.

I'm using v1.0.4552010 of Polyglot Notebooks, and the output indicates Plotly.NET.CSharp, 0.11.1 & Plotly.NET.Interactive, 4.2.1 is being installed.

And I just tried now and it works anyways, I think maybe me mixing both C# and F# might have broken it (or maybe the order?)

Thank you soo much for your help!

Still a weird error, never seen before. Happy that it works for you now 👍
