TastenTiger.Analyzers.Class.SealedByDefault

A Roslyn analyzer that ensures that classes and records which are not inherited anywhere are marked as sealed. This promotes clearer design intent, better performance, and safer code.

Why enforce sealed classes?

To prevent unintended inheritance
To improve runtime performance
To clarify design intent
To encourage deliberate API design

What this analyzer does

Produces the TA0002 compilation hint when a class or record:
- is not declared sealed
- and is not inherited anywhere in the solution
Provides a bulk quick fix to automatically add the sealed keyword to the class or record declaration.

Example

public class NotSealedClass // <-- triggers TA0002
{
}

public sealed class SealedClass // <-- compliant
{
}
