❔ how can i tell analyzer that function will always throw?

i want to do something like:

MyException.Throw(); // void Throw() => throw new Exception();

MyException.Throw(); // void Throw() => throw new Exception();

how can i tell analyzer, that code after that method won't be reachable?

Attributes interpreted by the C# compiler: Nullable static analysis...

Learn about attributes that are interpreted by the compiler to provide better static analysis for nullable and non-nullable reference types.

as far as i know and from some searching there isnt any other attribute to specify such behaviour

yeah, you cannot do this for general flow analysis the above attribute only affects nullable analysis, not definite assignment and such
