Having trouble with injection query

[bryankenote]

I am trying to get SQL highlighting in C# files.

I have this query located at ~/.config/nvim/after/queries/c_sharp/injections.scm

(invocation_expression
  function: (member_access_expression
	      expression: (identifier) @expression (#eq? @expression "Sql")
	      name: (identifier))
  arguments: (argument_list
	       (argument
		 (string_literal
		   (string_literal_fragment) @injection.content
		   (#set! injection.language "sql")))))

Here is a minimal example:

Sql.Raw("SELECT * FROM table LIMIT 10");

The query seems to be selecting the region of text with :EditQuery.

I have both the c_sharp and sql parsers installed

Looks like I needed to use ~/.config/nvim/queries/c_sharp/injections.scm instead of ~/.config/nvim/after/queries/c_sharp/injections.scm
