FXC: Error X3501: 'main': entrypoint not found

I am trying to compile a vertex shader using VS2013, but every time I try, FXC returns the following error:

Error error X3501: ‘main’: entrypoint not found

I’ve reduced the vertex shader to its simplest form and yet I’m still getting the same result:

DefaultVS.hlsl

#include "Include.hlsl"

cbuffer CameraTransform {
    float4x4 ViewProjMat;
};

VS_OUT main(VS_IN input) {
    VS_OUT result;

    result.Position = mul(input.Position, mul(input.WorldMat, ViewProjMat));

    return result;
}

Include.hlsl

struct VS_IN {
    float4 Position : POSITION;
    float4x4 WorldMat : INSTANCE_TRANSFORM;
};

struct VS_OUT {
    float4 Position : SV_POSITION;
};

And the properties of both files:
