The type of namespace name 'Shaders' and 'OpenTK' does not exist in the namespace 'Bonsai'

Dear Bonsai community,
I bumped into this problem while creating a customised C# transform. I have two computers with Bonsai installed. One of them (ver. 2.8.5) has no problem with using OpenTK and using Bonsai.Shaders (Bonsai-Shaders Library ver. 0.27.1) and can load that C# customised node. The other one (ver. 2.8.0) returned to this error when I placed the C# file into the extension (same version of Bonsai-Shaders Library though).

I thought perhaps that Bonsai was old so I installed Bonsai 2.9.0 (via portable) in that computer and tried to install all the packages. However, this time, I saw an additional error complaining about using OpenTK.
. On both Bonsai, the customised C# node can not be identified. Below is my C# script. Please feel free to let me know if there is anything wrong with that.
RandomSquare.zip

Best,
Chiyu

Hi @chiyu1203 have you also copied the Extensions.csproj file to those other machines? That file contains the necessary package references to load those libraries. I managed to load your random square extension in Bonsai 2.9.0 after installing the Bonsai.Shaders package and having this in Extensions.csproj (seems like OpenTK is already loaded as a dependency of Bonsai.Shaders).

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

  <ItemGroup>
    <PackageReference Include="Bonsai.Core" Version="2.9.0" />
    <PackageReference Include="Bonsai.Shaders" Version="2.9.0" />
  </ItemGroup>

</Project>
