Rhino Plugin (.rhp) — Windows-only, no Visual Studio required

For Windows-only plugins (Rhino 8, net48), reference Rhino DLLs directly via HintPath — no NuGet needed since the DLLs ship with Rhino:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net48</TargetFramework>
    <AssemblyName>MyPlugin</AssemblyName>
    <RootNamespace>MyPlugin</RootNamespace>
    <LangVersion>9.0</LangVersion>
    <Nullable>disable</Nullable>
    <Platforms>AnyCPU</Platforms>
    <OutputPath>bin\$(Configuration)\</OutputPath>
  </PropertyGroup>

  <ItemGroup>
    <!-- Rhino SDK — reference directly, never copy to output -->
    <Reference Include="RhinoCommon">
      <HintPath>C:\Program Files\Rhino 8\System\RhinoCommon.dll</HintPath>
      <Private>False</Private>
    </Reference>
    <Reference Include="Eto">
      <HintPath>C:\Program Files\Rhino 8\System\Eto.dll</HintPath>
      <Private>False</Private>
    </Reference>
    <Reference Include="Rhino.UI">
      <HintPath>C:\Program Files\Rhino 8\System\Rhino.UI.dll</HintPath>
      <Private>False</Private>

    <Reference Include="Newtonsoft.Json">
      <HintPath>C:\Program Files\Rhino 8\System\Newtonsoft.Json.dll</HintPath>
      <Private>False</Private>
    </Reference>
    <!-- These BCL assemblies must be listed explicitly for net48 SDK-style projects -->
    <Reference Include="System.Security" />
    <Reference Include="System.Net.Http" />
    <Reference Include="System.Drawing" />
  </ItemGroup>

  <!-- Post-build: rename .dll → .rhp so Rhino recognizes it as a plugin -->
  <!-- ONLY rename in output dir — do NOT auto-copy to AppData while Rhino may be running -->
  <Target Name="PostBuild" AfterTargets="PostBuildEvent">
    <Copy SourceFiles="$(OutputPath)$(AssemblyName).dll"
          DestinationFiles="$(OutputPath)$(AssemblyName).rhp" />
  </Target>
</Project>
