[just-ero]

Version Used

Compiler: 4.12.0-3.24470.4 (d799b05)
.NET: 9.0.100-rc.1.24452.12
Visual Studio Code: 1.93.1, 38c31bc77e0dd6ae88a4e9cc93428cc27a56ba40, x64
C# Extension: v2.49.25
C# Dev Kit Extension: v1.11.11

Steps to Reproduce

1. Create or open a C# project in Visual Studio Code (Visual Studio untested).
2. Set or add the following properties to an .editorconfig file that applies to the project:

   csharp_style_var_elsewhere             = false:suggestion
   csharp_style_var_when_type_is_apparent = true:suggestion
   

3. Add the following code wherever syntactically applicable:

   var e = E.A;
   enum E { A }

4. Observe the suggestion Use explicit type instead of 'var' (IDE0008) on the var keyword.

Expected Behavior

The suggestion is not emitted, as the type is quite apparent.

Actual Behavior

The suggestion is emitted.

The suggestion is not emitted for these snippets:

var e = default(E);

var e = new E();

This does seem like an 'apparent' case.
