how can I create [experimental] tag in c# which throws a compiler warning [duplicate]

Question

In c# I can mark some functions as obsolete by doing

[Obsolete]
void Foo()
{}

this tell the compiler to throw warning if I am using this function.

I want to create my own tag [Experimental] which just as obsolete throw a warning telling the user who build the code that this function is not well tested and using it may result in troubles.

Is it possible to do this? How?

Answer 1

I want to create my own attribute [Experimental] which just as [Obsolete] does makes the compiler produce a warning. Is it possible to do this?

No, sorry. Obsolete is a very special attribute. The compiler has special-purpose code written for it. There is no extensible warning mechanism in C#.
