Description

Calling Chart.toSVGString gives me:

Unhandled exception. System.MissingMethodException: Method not found: 'System.Threading.Tasks.Task`1<PuppeteerSharp.Browser> PuppeteerSharp.Puppeteer.LaunchAsync(PuppeteerSharp.LaunchOptions, Microsoft.Extensions.Logging.ILoggerFactory)'.

My code snippet:

// Api.chart is a GenericChart
open Giraffe.ViewEngine
let chartView = Api.chart |> Chart.toSVGString (Width = 800, Height = 600) |> Text

It looks like there's some issue calling a Puppeteer function?
I am on .NET 6 and running dotnet watch. I've tried PuppeteerSharp version 8.0.0 and 6.0.0 with no success.

Research direction

Start by reproducing the .NET 6 application at Program.fs line 44, where Chart.toSVGString is called, then inspect the Plotly.NET.ImageExport PuppeteerSharpRenderer call shown in the stack trace. Compare the PuppeteerSharp package versions and LaunchAsync signature involved; done means Chart.toSVGString completes without MissingMethodException.
