DotNet.Highcharts to Highsoft.HighCharts (9.3.2.1) Conversion - highcharts

Question

I've found an example online using the older DotNet.Highcharts api. https://www.c-sharpcorner.com/article/dotnet-highcharts-with-asp-net-mvc/. I'm trying to duplicate this using the newer Highsoft.Highcharts (9.3.2.1) api. There are a few syntax differences that I'm hoping I can get help with.
The style object is a hashtable. How can I convert the following to a hashtable?
Style = "fontWeight: 'bold', fontSize: '17px'"
The data values in the example are encapsulated in a Series object. In the new api there is no data object in the series. I'm guessing it corresponds to the Data object in the Chart. How can I change this to populate the data object?
columnChart.Series = (new Series[]
{
new Series{
Name = "Sachin Tendulkar",
Data = new Data(new object[] { 812, 412, 628, 1425, 460, 972, 204, 513, 315 })
},
new Series()
{
Name = "M S Dhoni",
Data = new Data(new object[] { 19, 895, 821, 1103, 1097, 1198, 600, 764, 524, })
}
}
How do I change this since there is no longer a BackgroundColorGradient?
BackgroundColor = new BackColorOrGradient(ColorTranslator.FromHtml("#FFADD8E6"))
This is what I have so far in the conversion:
Highcharts columnChart = new Highcharts();
columnChart.Chart = (new Chart()
{
Type = ChartType.Column,
BackgroundColor = "blue",
//Style = "fontWeight: 'bold', fontSize: '17px'",
BorderColor = "LightBlue",
BorderRadius = 0,
BorderWidth = 2
});
columnChart.Title = (new Title()
{
Text = "Sachin Vs Dhoni"
});
columnChart.Subtitle = (new Subtitle()
{
Text = "Played 9 Years Together From 2004 To 2012"
});
columnChart.XAxis = (new XAxis()
{
Type = "Category",
Title = new XAxisTitle()
{
Text = "Years",
Style = new System.Collections.Hashtable("fontWeight: 'bold', fontSize: '17px'")
},
Categories = new List<string> { "2004", "2005", "2006", "2007", "2008", "2009", "2010", "2011", "2012" }
});
columnChart.YAxis = (new YAxis()
{
Title = new YAxisTitle()
{
Text = "Runs",
Style = "fontWeight: 'bold', fontSize: '17px'"
},
ShowFirstLabel = true,
ShowLastLabel = true,
Min = 0
});
columnChart.Legend = (new Legend
{
Enabled = true,
BorderColor = "CornflowerBlue",
BorderRadius = 6,
//BackgroundColor = new BackColorOrGradient(ColorTranslator.FromHtml("#FFADD8E6"))
});
columnChart.Series = (new Series[]
{
new Series{
Name = "Sachin Tendulkar",
Data = new Data(new object[] { 812, 412, 628, 1425, 460, 972, 204, 513, 315 })
},
new Series()
{
Name = "M S Dhoni",
Data = new Data(new object[] { 19, 895, 821, 1103, 1097, 1198, 600, 764, 524, })
}
}
);
