Chart.ToBitmap - Method not found exception?
Hi All,
I am trying to generate a html-file as output with charts inside. First step is to generate base64 encoded png and use it as embed resource:
var start = temperCurve.Select(d => d.TimeStamp).Min(); var chartTemp = temperCurve.Chart(f => (f.TimeStamp - start).ToString(@"hh\:mm\:ss")) .AddYSeries(f => f.TempActual, name: nameof(TemperCurveDataDto.TempActual), seriesType: Util.SeriesType.Line) .AddYSeries(f => f.TempTarget, name: nameof(TemperCurveDataDto.TempTarget), seriesType: Util.SeriesType.Line) .AddYSeries(f => f.ProcessState, name: $"{nameof(TemperCurveDataDto.ProcessState)}", seriesType: Util.SeriesType.Line, useSecondaryYAxis: true); chartTemp.DumpInline($"Temperature, Start: {start:O}", 1920, 1080); var bmpTemp = chartTemp.ToBitmap(1920, 1080); ...
But I get a MissingMethodException
- Method not found: 'System.Drawing.Bitmap LINQPad.ChartExtensions.ToBitmap(LINQPad.LINQPadChart, Int32, Int32)'.
Is this a bug or is there something wrong in my code?
Tanks!

If I create a new query with a simple chart,
then I have no problem calling the .ToBitmap extension
There seems to be a problem with the NuGet references.
Some of the custom packages use overriding extensions.
I'm surprised LINQPad didn't require you to clarify which extension method you're attempting call. I certainly get that with conflicting enums and classes (Newtonsoft.Json vs System.Xml is a prime example).
