How to make this shader compatible with LWRP ?

Hi Guys !

i'm trying to make this shader compatible with the LWRP, but without succes...
Is there a solution ? Please give me examples, i'm not a Shader Badass !

Thank you !

Code (csharp):

1. Shader "Custom/Sin Wave" {
2.     Properties{
3.         _Tile("Tile", Range(0.0,1.0)) = 0.5
4.         _Color ("Color", Color) = (1.0,1.0,1.0,0.5)
5.         _ForegroundColor("Foreground Color", Color) = (1,1,1,0)
6.         _BackgroundColor("Background Color", Color) = (0,0,0,0)
7.         _ForegroundMask("Foreground Mask", 2D) = "white" {}
8.         _ForegroundCutoff("Foreground Cutoff", Range(0,1)) = 0.5
9.         _BackgroundCutoff("Background Cutoff", Range(0,1)) = 0.5
10.         _Radius("Radius", Range(0.0,1.0)) = 0.5
11.     }
12.         SubShader
13.         {
14.             Tags {"Queue"="Transparent" "IgnoreProjector"="True" "RenderType"="Transparent" }
15.  
16.             Lighting Off
17.             LOD 100
18.             ZWrite Off
19.             Blend SrcAlpha OneMinusSrcAlpha
20.             CGPROGRAM
21.  
22.             #pragma surface surf Standard alpha:fade
23.             #pragma target 3.0
24.  
25.             sampler2D _ForegroundMask;
26.             struct Input {
27.             float2 uv_ForegroundMask;
28.         };
29.  
30.         fixed4 _ForegroundColor;
31.         fixed4 _BackgroundColor;
32.         fixed4 _Color;
33.         half _ForegroundCutoff;
34.         half _BackgroundCutoff;
35.         half _Radius;
36.         half _Tile;
37.  
38.         void surf(Input IN, inout SurfaceOutputStandard color:alpha)
39.         {
40.  
41.             fixed x = (-0.5 + IN.uv_ForegroundMask.x) * _Tile;
42.             fixed y = (-0.5 + IN.uv_ForegroundMask.y) * 2;
43.             fixed radius = 0.5 + sin(x * 3.1415926535) * _Radius;
44.             radius -= (0.5 * y + 0.5);
45.             clip(radius - _BackgroundCutoff);
46.             clip(_ForegroundCutoff - radius);
47.             color.Albedo = _Color;
48.             color.Alpha = _Color.a;
49.         }
50.             ENDCG
51.     }
52.     FallBack "Unlit/Transparent"
53.    
54. }
