In my recent project, Everything went smooth but at the end of the project when we delivered code to client, We got comment from client on naming convention.
In code, at few places naming convention for .NET C# coding was not followed hence we had to change it. It’s really good practice to follow naming convention from the beginning of the project. Event if you are working on sample or test project, Try to follow the naming convention and after some time it will become your habit 🙂
