X4717 Effects deprecated for D3DCompiler_47

I started to learn while coding some basic Direct3D 11 functionality.

My current code compiles and runs fine, but I still obtain:

X4717 Effects deprecated for D3DCompiler_47

I use only one .fx file named effect.fx:

//--------------------------------------------------------------------------------------
// ModelTransform Variables
//--------------------------------------------------------------------------------------
cbuffer ModelTransform : register(b0) {
    matrix model_to_world;
    matrix world_to_view;
    matrix view_to_projection;
}

//-----------------------------------------------------------------------------
// Vertex Shader
//-----------------------------------------------------------------------------
struct VS_OUTPUT {
    float4 p : SV_POSITION;
    float4 diffuse : COLOR0;
};

VS_OUTPUT VS(float4 p : POSITION, float4 diffuse : COLOR) {
    VS_OUTPUT output = (VS_OUTPUT)0;
    output.p = mul(p, model_to_world);
    output.p = mul(output.p, world_to_view);
    output.p = mul(output.p, view_to_projection);
    output.diffuse = diffuse;
    return output;
}

//-----------------------------------------------------------------------------
// Pixel Shader
//-----------------------------------------------------------------------------
float4 PS(VS_OUTPUT input) : SV_Target {
    return input.diffuse;
}

which I compile at runtime

const HRESULT result_vertex_shader_blob = CompileShaderFromFile(L"Project 4/shaders/effect.fx", "VS", "vs_4_0", &vertex_shader_blob);
const HRESULT result_pixel_shader_blob = CompileShaderFromFile(L"Project 4/shaders/effect.fx", "PS", "ps_4_0", &pixel_shader_blob);

These methods eventually call

D3DCompileFromFile

Should I break the code in one .vs and .ps file?

There is some discussion about Effects 11. But it doesn't really help.
