How to restrict class usage

Question

Is there a way to enforce a class only to be used in ASP.NET ? So that it can't be referenced in a WinForm app or throw exception when instantiated. Is there some kind of .NET class attribute for this purpose?

Answer 1

Don't!!!

public class WebOnly
{
    public WebOnly()
    {
        if (HttpContext.Current == null)
            throw new Exception("me needs web");
    }
}
