dotnet framework : How to write a .NET attribute which does just like ObsoleteAttribute...

You can't... ObsoleteAttribute is handled as a special-case by the
compiler, not by anything extensible.

What do you want to check, in particular? There may be other ways of
doing it...

Hi,

AFAIK there is no way of doing that. The compiler knows a given number
of attributes and have CODED actions for them.

Hi,

In .NET there is attribute named ObsoleteAttribute which is derived from
System.Attribute Class. This attribute when applied to a target (class or
method etc.) gives a compiler warning/error. I know we can write our own
attributes by inheriting the System.Attribute but I want to make it give
compiler warning or error when it is applied on the defined attribute
target.

How can we write such an attributes?

Regards,
Ashok G
