RhinoCommon with net7.0 target?

Goswin · February 27, 2025, 4:42pm

Are there any plans for publishing the RhinoCommon Nuget with a net7.0 target ?

I know there are workarounds like <NoWarn>NU1701</NoWarn> but still other problems like
A reference to the type 'System.Drawing.Bitmap' in assembly 'System.Drawing' was found, but the type could not be found in that assembly
pop up and make building for net7.0 hard and frustrating. I have not been able to solve this one with a System.Drawing.Common reference.

I maintain a plugin that loads other RhinoCommon libraries from Nuget dynamical and does its own dependency resolution. (via dotnet restore) It would be great if I could publish those RhinoCommon libraries correctlly multitargeting net48 and net7.0 on Nuget.

I just realized this actually planned since a year: https://mcneel.myjetbrains.com/youtrack/issue/RH-77311/Add-.NET-7-target-to-nuget-packages

You can reference System.Drawing.Common in your netcore build

github.com/mcneel/RhinoVisualStudioExtensions

Rhino.Templates/content/CSRhino/MyRhino.1.csproj

2bc5f3094


      
          <!--#endif-->
          <!--#if (UseWinForms)-->
            <!-- Reference WinForms for .NET 7.0 on macOS -->
            <ItemGroup Condition="!($(TargetFramework.Contains('-windows')) or $(TargetFramework.StartsWith('net4')))">
              <!-- Rhino 8.11 and later you can use this -->
              <!-- <FrameworkReference Include="Microsoft.WindowsDesktop.App.WindowsForms" /> -->
              
              <!-- Rhino 8.10 and earlier -->
              <PackageReference Include="Microsoft.NETFramework.ReferenceAssemblies.net48" Version="1.0.3" ExcludeAssets="all" GeneratePathProperty="true" />
              <Reference Include="$(PkgMicrosoft_NETFramework_ReferenceAssemblies_net48)\build\.NETFramework\v4.8\System.Windows.Forms.dll" Private="False" />
              <PackageReference Include="System.Drawing.Common" Version="7.0.0" ExcludeAssets="runtime" />
            </ItemGroup>
          
          <!--#endif-->
          <!--#if (RhinoVersion < '8')-->
            <Target Name="CopyPdbForMonoDebugging" AfterTargets="AfterBuild">
              <!-- Enable debugging in Rhino 6/7 on Mac -->
              <Copy SourceFiles="$(TargetDir)$(TargetName).pdb" DestinationFiles="$(TargetDir)$(TargetName).rhp.pdb" Condition="$([MSBuild]::IsOSPlatform(OSX)) and $(TargetFramework.StartsWith('net4')) and Exists('$(TargetDir)$(TargetName).pdb')" />
            </Target>
          
          <!--#endif-->

It also shows how to reference System.Windows.Forms from a net7.0 project so you can do GH stuff on Mac

I had already a reference to System.Drawing.Common. I still get A reference to the type 'System.Drawing.Bitmap' in assembly 'System.Drawing' was found, but the type could not be found in that assembly see fails to build targeting net7.0 · Issue #2 · goswinr/Rhino.Scripting · GitHub on how to reproduce.
