Hi,

I need to implement a HtmlHelper extension in my MVC project simply just to output some string but ONLY in the DEBUG mode, not in REALEASE. My first attempt would be:

[Conditional("DEBUG")]
public static string TestStringForDebugOnly(this HtmlHelper helper, string testString)
{
return testString;
}

But obviously that would give a compile error: "The Conditional attribute is not valid because its return type is not void."

So my understanding is once you set [Condition] attribute, it doesnt allow to return anything? why? What is other way to implement this kind of function? anyone help would be much appreciated.

Thanks!
