Hello. I’m developing a rhino plug-in ( XHull) using visual studio preview 2022 and rhinoCommon 8.0.23304.9001. Up to now ( before i updated Rhino for the latest version … (which is may be not related ?)) everything was working perfectly: the plug-in was loading by itself But now the plug-in doesn’t load anymore when I launch it from visual studio (I get an error message from Rhino saying “Unable to load XHull.rhp plug-in: initialisation fail”. The plug-in doesn’t seems to be responsible because I can load it “manually” from Rhino with the command : tools /options/… " Load plug-in" Also, if I shut off Visual studio and run Rhino by itself , the “load plug in” command doesn’t work anymore . Can someone help ? Thanks

We need more information. Depending upon how old your project file is, you will have different properties screens for the project.
How are you launching from Visual Studio when you debug?
If your project properties look like these, show us a screenshot:
If you have a newer project format, you will have debug profiles in your project properties, so show us this:
You may also need to set whether you are launching rhino in .Net Core mode or .Net Framework mode. What are you building for Core or FW? If you are targeting .Net 4.8 you have to pass the /netfx switch to rhino on startup, otherwise it won’t be able to load your plugin.
Let us know a little more about your scenario and we can help.

Hello Dale , here it is
XHull.rhp (10.5 KB)
Hello Jason. Following your request i see that there might be a problem with the Environment variable ? Also I built with Rhino 8 netcore. As for the target frame work, at the beginning i was using the template’s default values which are net7.0;net48 but i tried net8.0 .
Hope this to clarify and thanks for your help ! Johnny
Johnny,
Looks like that plugin has a dependency on XUtils 1.0.0.0 so I don’t think @dale will be able to load that plugin, unless you also include that dll.
I see you’ve referenced RhinoCommon 8.13.24317.13001, are you sure have that NuGet package and at least that version of Rhino installed?
I don’t see that you are overriding the default plugin load behavior, so it won’t currently load your plugin until you execute one of the rhino commands in the plugin.
Have you tried running the command: XHullCommand to see if it loads your plugin?
If you want it to load on startup, you can change that behavior in your plugin class.
The default behavior of Rhino is to only load your plugin when needed (like you execute a command):
If in your plugin class you override this behavior, it could load on startup:
Hello Jason and the others helping. I confirm that i do have the right Rhino version is Rhino 8 SR13 2024-11-12 (Rhino 8, 8.13.24317.13001) as you can see in the system info file that i sent to Matt. Anyway the problem is now solved. Here is what i did : 1- I clean up the registry of any trace of the previous plug-in . 2- I had created a new plug in and simply made reference of the previous plug in code and it work perfectly without any other modification. Thanks everyone for your help
