Steps to reproduce

1. On MainWindow.xmal add code:

 <oxyplot:PlotView x:Name="MyOxyPlotView">
        </oxyplot:PlotView>

2. On MainWindow.xmal.cs add code:

            var model = new OxyPlot.PlotModel();
            model.Axes.Add(new LinearAxis()
            {
                Position = AxisPosition.Bottom
            });

            MyOxyPlotView.Model = model;

3. Debug the app :

throw an exception:

System.BadImageFormatException
  HResult=0x8007000B
  Message=试图加载格式不正确的程序。 (异常来自 HRESULT:0x8007000B)

but I change the .net version to: netcoreapp3.1, debug no throw exception

Platform: WPF,
.NET version: netframework 4.5 or 4.8

<PackageReference Include="OxyPlot.SkiaSharp.Wpf" Version="2.1.0-Preview1" />

This is probably because SkiaSharp has native dependencies, which means you need to be using the appropriate version of the framework (x86/x64) to run it; you can't get away with AnyCpu. You will need to commit to a target-platform for .NET framework.

There is some slightly confused discussion here: #1514 (comment) . You can find an example csproj depending on SkiaSharp here: https://github.com/oxyplot/oxyplot/blob/develop/Source/OxyPlot.SkiaSharp.Tests/OxyPlot.SkiaSharp.Tests.csproj

thanks, it's works.
