Crash when built with Visual Studio 2026, C# 10 and PublishSingleFile=true;SelfContained=true

[MRoc]

Describe the bug

When building a WPF app with H.NotifyIcon.Wpf version 2.3.2 in Visual Studio 2026, using C# 10 and PublishSingleFile=true; SelfContained=true, the app crashes with the error shown below.

To reproduce the issue, I created a small example app, described here: https://github.com/MRoc/H.NotifyIcon-Crash

Steps to reproduce the bug

1. Clone the example repo https://github.com/MRoc/H.NotifyIcon-Crash
2. Open PowerShell
3. Run ./Publish.ps1
4. Run ./WpfApp1\publish\WpfApp1.exe

Expected behavior

The blank example window opens.

Actual behavior

A message box with the following error appears:

I assume the problem is due to H.NotifyIcon.Apps.Wpf\H.NotifyIcon.Apps.Wpf.csproj referencing System.Drawing.Common with explicit version number 9.0.1:

  <ItemGroup>
    <PackageReference Include="DependencyPropertyGenerator" Version="1.5.0">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>compile; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
    <PackageReference Include="System.Drawing.Common" Version="9.0.1" />
    <PackageReference Include="System.Resources.Extensions" Version="9.0.1" PrivateAssets="All" />
  </ItemGroup>

I am experiencing same issue with 2.4.1.
In my case it is caused by SelfContained=True

Is there some progress about this? I have PublishSingleFile=false and it occurs also
