problem with .net8 windows application

[behroozbc]

Hi, I wanted to install and use this package on my windows form with .net 8 but I got this error message. this is the cs proj file

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net8.0-windows</TargetFramework>
    <Nullable>enable</Nullable>
    <UseWindowsForms>true</UseWindowsForms>
    <ImplicitUsings>enable</ImplicitUsings>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="ScottPlot" Version="5.0.45" />
    <PackageReference Include="Spectrogram" Version="1.6.1" />
  </ItemGroup>

</Project>

I think the package should not have depend on System.Drawing.Common version 4.6 and use imagesharp

Hi @behroozbc, thanks for this question!

Microsoft sunset support for System.Drawing.Common in .NET 6, leading to this issue 😅 Although you could target .NET 5, there is probably a better option:

In the NuGet explorer you can click the "preview" checkbox to enable installing preview packages. The latest Spectrogram version is actually 2.0.0-alpha and it should work on modern .NET targets

Let me know if this does the trick!

FYI, Spectrogram is migrating to SkiaSharp instead of ImageSharp because SkiaSharp is officially supported by Microsoft https://www.nuget.org/packages/SkiaSharp/ but ImageSharp is not and it is also not free https://sixlabors.com/pricing/

I did not know about the plan to switch to ShiaSharp!!! Can I help you in this progress??

Thanks for your offer! I think the switch has already happened so most of the work is complete. It's still a preview package just because I haven't reviewed the API yet (I may want to refine it) and update the docs at the same time.

It's on my to-do list for this weekend now though 😎
