While working on a team, code consistency is of great value. If coding style is not consistent, it increases Refactoring, Maintenance time. By default , Visual Studio provides suggestion for naming inconsistency of Interface and Types. However, based on the organisation and type of projects , naming style can differ. We can override the default coding style based on our purpose. If coding style is set in Visual Studio, it applies to all projects that are opened in it. However, visual studio provides an option to generate .editorconfig file based on our naming style configuration in visual studio. We can use the generated editorconfig file on root of our project to apply it on project basis.
To add/change coding style in Visual Studio
- Goto tools → Options → Text Editor → c# → Code Style → Naming
- Add/update styles by clicking + icon and set styles of your choice.
- Set severity option based on how strict you want to enforce the style. I generally prefer using Error severity level.
After it is done, you will see the styles in opened files that are not compatible with your convention.
If you want to enforce it on project basis,
- Set styles as mentioned above.
- Generate .editorconfig file by
-
Goto Tools -> Options -> Text Editor -> C# -> Code Style -
You will see a button stating "Generate .editorconfig file from settings" -
Once this is done, copy generated file to root of the project
Below is the .editorconfig I generally prefer and use
# Remove the line below if you want to inherit .editorconfig settings from higher directories
root = true
# C# files
[*.cs]
