// The recommended way to create shaders is to use GetShaders method on EffectsManager (or GetVertexShader, GetPixelShader or other methods - see below).
// In order for EffectsManager to get the shader resources, we need to RegisterShaderResource before the shaders can be created.
// In this case the code in CustomShaderMaterialSample.xaml.cs does that. The following code is used:
//var directoryShaderBytecodeProvider = new DirectoryShaderBytecodeProvider(System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Resources\\Shaders"));
//dxDevice.EffectsManager.RegisterShaderResource(directoryShaderBytecodeProvider);
var vertexLayoutDesc = InputElementFactory.GetInputElementsArray(InputLayoutType.Position | InputLayoutType.Normal);
dxDevice.EffectsManager.GetShaders(
"MeshNormalShader.vs", "MeshNormalShader.ps", vertexLayoutDesc,
out _vertexShaderSharedResource, out _pixelShaderSharedResource, out _inputLayoutSharedResource,
throwExceptionIfShadersNotFound: true);
// You could also use GetVertexShader and GetPixelShader methods:
//_vertexShaderSharedResource = dxDevice.EffectsManager.GetVertexShader("MeshNormalShader.vs", vertexLayoutDesc, out _inputLayoutSharedResource, throwExceptionIfNotFound: true);
//_pixelShaderSharedResource = dxDevice.EffectsManager.GetPixelShader("MeshNormalShader.ps", throwExceptionIfNotFound: true);
// You could also use simple shader constructors to create the shaders:
//// Create VertexShader
//byte[] vertexShaderBytecode = System.IO.File.ReadAllBytes(System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Resources\\Shaders\\MeshNormalShader.vs"));
//_vertexShader = new VertexShader(parentDXDevice.Device, vertexShaderBytecode);
//// Create InputLayout
//_inputLayout = new InputLayout(parentDXDevice.Device, vertexShaderBytecode, vertexLayoutDesc);
//// Create Pixel shader
//byte[] pixelShaderBytecode = System.IO.File.ReadAllBytes(System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Resources\\Shaders\\MeshNormalShader.ps"));
//_pixelShader = new PixelShader(parentDXDevice.Device, pixelShaderBytecode);
//// If we are using debug device we set DebugName - so we can see the correct name of shaders in Graphic debugging
//if (parentDXDevice.IsDebugDevice)
//{
// _vertexShader.DebugName = EffectName + "_VertexShader";
// _inputLayout.DebugName = EffectName + "_InputLayout";
// _pixelShader.DebugName = EffectName + "_PixelShader";
