--check option does not work

The new dotnet format --check does not seem to work. I would assume that it only shows if the .editorconfig rules have been applied or not but does not touch my files.

Steps to reproduce

1. Create a new project

dotnet new console -n Test
cd Test

2. Add .editorconfig

root = true

[*.cs]
csharp_new_line_before_open_brace = false

3. Run check option

dotnet format --check

Expected outcome

The dotnet format --check command fails with non-zero exit code, beacse Program.cs does not apply to the csharp_new_line_before_open_brace = false rule.

Actual outcome

The Program.cs file gets reformatted and the dotnet format --check` command completes successfully.

Hi,

I was trying the same command: dotnet format --dry-run --check, but though the file was not modified, the command executed successfully. This was the rule I had: csharp_new_line_before_else = true if (i == 0) { Console.WriteLine("i is 0"); }else { Console.WriteLine("i is not 0"); }

This is what I ran:

dotnet format --check --dry-run Formatting code files in workspace ‘**\ConsoleApp1\ConsoleApp1.sln’. Formatting code files in project ‘ConsoleApp1’. Formatted code file ‘Program.cs’. Format complete.

If I run just --check, it formats the page, when I run dotnet format --dry-run --check, nothing happens to the file and the errors are not reported as well. Any help is appreciated.

Thanks!
