How to implement Vortice.Direct3D.Include in 1.9.77+

Hello 😃,

I’ve been using v1.9.65 of Vortice.D3DCompiler/VorticeDirect3D11 to compile shaders like this

var include = new ShaderFileInclude(Path.GetDirectoryName(this.FullPath)); 
Compiler.Compile(sourceText, Defines, include, this.VertexShaderEntryPoint, this.FileName, this.VertexShaderProfile, out this.vertexShaderBlob, out var vsErrorBlob);

The class ShaderFileInclude looks like this:

    internal sealed class ShaderFileInclude : Vortice.Direct3D.Include
    {
        private readonly string RootFolder;
        public ShaderFileInclude(string rootFolder)
        {
            this.RootFolder = rootFolder;
        }

        public ShadowContainer Shadow { get; set; } // never set, property is null!

        public void Close(Stream stream) => stream.Close();

        public Stream Open(IncludeType type, string fileName, Stream parentStream)
        {
            switch (type)
            {
                case IncludeType.Local:
                    return File.OpenRead(Path.Combine(this.RootFolder, fileName));
                case IncludeType.System:
                default:
                    return File.OpenRead(fileName);
            }
        }

        public void Dispose() { }
    }

This worked great. However when upgrading to a newer version (1.9.77 or higher). This leads to a System.NullReferenceException, I think because I haven’t initialized the ShadowContainer Shadow property. To be honest I don’t really know what to do with it. I’ve looked through the source code in this repository. But I can’t really figure out how to implement the Vortice.Direct3D.Include correctly or more specifically how to initialize the Shadow property.

Any hints?
