Bug string interpolation bug inside macro and namespace

when i use @$ for complex string , i get a error message in inspector : "No MonoBehaviour scripts in the file, or their names do not match the file name" ,then i simplify the code as below:

Code (CSharp):

1. using UnityEngine;
2.  
3. namespace MySpace
4. {
5.     public class TestStr : MonoBehaviour
6.     {
7.         void Awake()
8.         {
9. #if UNITY_EDITOR
10.             var str = @$"";
11. #endif
12.         }
13.     }
14. }

interesting thing is when delete namespace or "#if xxx" macro ,the error gone
unity ver:2020.3.1f1

 

Are you sure you're not getting compiler errors in your console? I do:
Assets\TestStr.cs(10,27): error CS1525: Invalid expression term ''
Assets\TestStr.cs(10,27): error CS1646: Keyword, identifier, or string expected after verbatim specifier: @
Assets\TestStr.cs(10,28): error CS1002: ; expected

There's warning in the docs: Starting with C# 8.0, you can use the $ and @ tokens in any order: both $@"..." and @$"..." are valid interpolated verbatim strings. In earlier C# versions, the $ token must appear before the @ token.

If I use $@ instead of @$, everything works fine.

 

no error here, i can enter play mode ,of course this script will not load

it's good.

what i mean is the unity do support @$ ，but if "@$" is inside namespace and macro ,@$ will cause strange error and this error is not in console,
