   @awesomeinsight I have already updated the package to work with .net core, but the issue that you are mentioning is not due to the framework version but a problem related to the mixed-use of unmanaged Code(c++) and managed Code(C#).

   I experienced the same problem and endep up solving it in the following way:

   public class NonCollectibleAssemblyLoadContext : AssemblyLoadContext
       {
           public NonCollectibleAssemblyLoadContext() : base(isCollectible: false)
           {
           }
       }
   
   
           var loadContext = new NonCollectibleAssemblyLoadContext();
               var assemblyPath = @"C:\location\of\your\dll\DracoWrapper.dll";
               Assembly mixedModeAssembly = loadContext.LoadFromAssemblyPath(assemblyPath);
   
               var gltfDecoderType = mixedModeAssembly.GetType("dracowrapper.GltfDecoder");
               var gltfDecoderInstance = Activator.CreateInstance(gltfDecoderType);
   
               var decodeFromFileToSceneMethod = gltfDecoderType.GetMethod("DecodeFromFileToScene");
               var res = decodeFromFileToSceneMethod.Invoke(gltfDecoderInstance, new object[] { fileToCompress });
               var resType = res.GetType();
               var valueMethod = resType.GetMethod("Value");
               var scene = valueMethod.Invoke(res, null);
   
               var dracoCompressionOptionsType = mixedModeAssembly.GetType("dracowrapper.DracoCompressionOptions");
               var dracoCompressionOptionsInstance = Activator.CreateInstance(dracoCompressionOptionsType);
   
               var sceneUtilsType = mixedModeAssembly.GetType("dracowrapper.SceneUtils");
               var setDracoCompressionOptionsMethod = sceneUtilsType.GetMethod("SetDracoCompressionOptions");
               setDracoCompressionOptionsMethod.Invoke(null, new object[] { dracoCompressionOptionsInstance, scene });
   
               var gltfEncoderType = mixedModeAssembly.GetType("dracowrapper.GltfEncoder");
               var gltfEncoderInstance = Activator.CreateInstance(gltfEncoderType);
               var encodeSceneToFileMethod = gltfEncoderType.GetMethod("EncodeSceneToFile");
               encodeSceneToFileMethod.Invoke(gltfEncoderInstance, new object[] { scene, fileToCompressTemp });
   
   

   I hope this helps

   thanks anyway!
   yes, the limitation is due to the mix compilation, as i've mentioned in #4 , which makes this wrapper not-so-ideally works under windows only.

   Recently i've already seen pure C# port of Google Draco (only Draco, not Draco-ed glTF), check it out here: https://github.com/fileformat-drako/FileFormat.Drako-for-.NET, and it is hopefully to be a more cross-platform-able solution.
