Code Quality: Enforce code style in EditorConfig

[Lamparter]

Description

Currently, there is a code style, Website:"docs/contributing/code-style". However, this would be better if it was enforced throughout the codebase through the editorconfig file in the root directory.

Concerned code

Files/.editorconfig

Lines 3 to 6 in e7d00f3

	[**/*.cs]
	indent_style = tab
	indent_size = 4
	tab_width = 4

Gains

• Code style is automatically enforced
• Less need for review to check if new contributors have used the code style

Requirements

• Implement the code style in the editorconfig as specified by Website:"docs/contributing/code-style".

Comments

I did a first draft here, I'll create a PR for it when this issue is marked ready to build.

I thought we had this at one point. @lukeblevins do you have any recollection?

[0x5bfa]

I think it's good idea but some values are default so can be deducted.
@yaira2 i guess that's this #2781?

[lukeblevins]

Visual Studio might have not supported editorconfig preferences for XAML. I don't recall whether that's changed

[Lamparter]

@yaira2 would you like to move forward with this?

[0x5bfa]

Once you made a PR, I'll shortly review it out.

[yaira2]

If I remember correctly, the last time this was discussed, we concluded that it would be better to add a check before merging PRs, similar to what we do for XAML.

[0x5bfa]

Did we? but it's a great idea. We should use "dotnet format" and specify changed files for each.
Ctrl+S doesn't format automatically like XamlStyler so we can do that any time before or after

[Lamparter]

Yes exactly. Visual Studio's code cleanup feature is also based on this file.
