Rider - Unity shader code completion doesn't work outside CGPROGRAM/ENDCG field

Hi,
Just start using Rider for unity coding and pretty cool on C# coding, but when I try on shader, the code completion doesn't work outside the field of CGPROGRAM/ENDCG.

For instance, the Properties block, all the type of data can't be auto-completed.

And:
#pragma vertex vert / #pragma fragment frag
the "#pragma" can be recognized, but the "vertex" and "fragment" can't be.

I read the manual of Rider on the official site and I found the image on the manual shows this should be working.

is there any settings I didn't finish?

Here is the system info:
